1. Everything Falls at the Same Speed
Many people find this concept difficult to accept. The weight of an object has no impact on its rate of descent. Heavy objects fall at the same speed as light objects, due to the effects of gravity and air resistance. Only two factors affect how quickly an object falls — gravity and air resistance. If you remove either one, it will take the same amount of time for a feather or a bowling ball to reach the ground.
2. Particles Can Behave Differently When Observed
When it comes to the quantum world, things can get pretty weird. Quantum physics has a lot of amazing facts that could make this list: particles like electrons behave as waves both when we’re not looking at them and when we are, called duality by physicists. This property is due to the fact that particles appear differently depending on whether or not an observer is present. For example, an electron appears as a particle when viewed using a detector, but behaves as a wave if observed without being detected. However, you will find it shows the properties of the wave when you are not observing with a detector. This can be explained by the double-slit experiment.
3. We Can Observe Less Than 5% of the Stuff in the Universe
Scientists have spent a lot of time studying the universe. We know a great deal about the elements, light, electricity, and even stars. However, we only see a tiny fraction of what exists in the universe — 95% is made up of Dark Matter and Dark Energy that we cannot see or touch. If you’re wondering how scientists can claim to know anything about this mysterious matter if it’s invisible to us, then you are thinking like a physicist. That’s a great question. We know it’s there because it affects the way that galaxies move. We can measure the speed at which galaxies spin and calculate how much mass there should be. It turns out there is a lot more than we can account for.
4. The touch screen of your phone is based on YOU!
Don’t be surprised if physics provides most of the answers. Based on the equation for resistance, electrons in your body repel objects when you touch a phone’s screen. This broken circuit causes a potential drop, which is detected by a sensor and results in an appropriate response being implemented.
5. Time Freezes Inside a Black Hole
One of the most innovative findings of the 20th century was the relativity of time. In a few films you have seen that time stops, it freezes, imagine flash, for instance, time can run gradually for him. Physics can explain that in case you think this is stupid but consider now not in that movie. life would be brilliant if you could freeze time, isn’t it? it’s far possible within the black hollow, at the occasion horizon. however, it’s a bit elaborate, no longer for the only one who’s falling into the black hollow however to a distant observer the time interior freezes. this is viable because of gravitational time dilation. For black holes, time, a second turn into infinitely lengthy that there exists singularity, which means time tends to freeze. So a distant observer would look at the time almost paused or frozen inner a black hole.
6. Steel is More Elastic Than Rubber
We generally understand that material is elastic if it can stretch and return to its original shape quickly after being deformed. This is based on the physical properties of matter called elasticity which states that a material will regain its original form after being stretched or distorted. While you might not believe this about steel, physics dictates otherwise. In fact, steel is much more elastic than rubber; this is why it’s used for things like bridges and buildings because when deformed, it recovers quickly and is better than rubber.
7. GPS works on Physics formula
Modern applications like GPS that help us find our way in life are based on a physics formula called E=mc2. Satellite navigation systems use geostationary satellites to precisely pinpoint locations and communicate using radio waves. This is why the theory of relativity helps with the proper functioning of GPS systems. It’s interesting stuff, ladies! The astronauts who are currently living in the International Space Station experience time slowly due to their different rates of velocity and gravity. This is why they sometimes look younger than what we’re used to seeing them as.
8. The Science of “Dead Sea”
Nature’s way of proving that physics is cool is proven in the manner of the dead Sea that’s one such marvel recognized for its density because of the presence of salt in this sea, A person can without problems drift in the water without drowning. So, you don’t need to be a swimmer to experience the useless Sea.
9. Water Can Boil and Freeze at the Same Temperature
Water can freeze and boil at the same temperature. This occurs because water has three phases — ice, liquid, and vapor-at a particular point in space. At this point, all three are present simultaneously. This means that boiling water is also possible as well as freezing it at its normal temperature of 0 degrees Celsius ©.
Decreasing pressure can lead to a decrease in boiling point and an increase in freezing point. So, at a temperature of 273.16 K (0.01 C or 32.02 F) and a pressure of 0.006 Pascals, water can freeze as well as boil. All three states of water coexist. This is not only true for water but for other matters too.
10. Light Move Slowly Inside the Sun
One of the most vital capabilities of light is that it’s speedy — VERY fast. In fact, not anything within the universe can journey faster than the velocity of light. It takes approximately 8 minutes for light from the solar to travel approximately 93,000,000 miles (150,000,000 km) to attain the Earth. so that you would possibly discover it hard to agree with that it takes longer for it to go the shorter distance of 440,000 miles (700,000 km ) from the middle of the sun to the brink. In fact, it takes lots longer — around 100,000 years. Why does this manifest? properly, the rate of light isn’t regular. much like a vehicle can pass faster on a road than it may on the sand, some substances sluggish light down. That’s why things appear distinct underwater. The denser the material, the extra the light is slowed down. It takes to see you later for a photon to tour through the sun because it’s surely densely packed.
11. Wave-particle duality
At first glance, particles (like electrons) and waves (like light) cannot be the same. They are two entirely different forms of matter- a solid state versus a beam of energy. However, it has been proven time and again that both light and electrons can act as both particles and waves. This seems crazy, but there is evidence to support this theory. For example, light can also behave like a waveform when observed with an electron microscope. In addition, experiments have shown that particles like electrons exist within fields of electromagnetic radiation just as surely as waves do!
12. Movement against the gravity
It is believed that everything on Earth moves according to gravitational force, but this isn’t always true. In some cases, particles can move against gravity and resist being pulled down by it. For example, water can easily flow up narrow channels without any help from the gravitational force. This proves that the gravitational force cannot control every particle in existence. There are also cases where another physical force might override it; for example surface tension.
13. Quantum Entanglement
Quantum mechanics is the study of physics at the atomic level, including the behavior of subatomic particles. These are tiny particles that makeup everything in existence; quantum entanglement is a process by which two or more subatomic particles become linked so their states are essentially identical. This occurs when measurements on one particle automatically determine the state of the other particles as well. This means that if you change the spin of one particle in an opposite direction, the other particles will react the same way, no matter where are they, this indicates that the information can be teleported anywhere in the universe.
14. All matter is energy
It has been proved that energy and matter are the two sides of the same coin. According to Einstein’s mass-energy equivalence, E = mc2, energy stored in any particular mass is determined by the conversion factor of c squared, where c is the speed of light. This indicates that the mass of any object increases as it approaches the speed of light.
15. We are electrical creatures.
Positive and negative charges are present throughout our bodies, sending electrical signals that control heart rate and protect certain cells. When we come into contact with something that has an opposing electrical charge, such as metal against plastic, the resulting ions are easily visible. This phenomenon is especially prominent during winter months due to the accumulation of negatively charged particles on surfaces made from materials like plastics.
