Because of differences in gravity, a 200 pound person would only weigh 76 pounds on Mars.
- Light from the Earth takes just 1.255 seconds to reach the Moon.
- Sound travels at a speed of around 767 miles per hour (1,230 kilometres per hour).
- When traveling at 80 kilometres per hour (50 miles per hour), cars use around half of their fuel just to overcome wind resistance.
- Water can work against gravity, moving up narrow tubes in a process called capillary action.
- A magnifying glass uses the properties of a convex shaped lens to magnify an image, making it easier to see.
- A scientist who studies physics is known as a physicist.
- Uranus is the only planet in our solar system that rolls on its side like a barrel, while Venus is the only planet that spins in the opposite direction to Earth.
- The fastest land animal in the world is the Cheetah clocking a max speed of around 113 km per hour (70 mph).
-
1921 Nobel Prize in Physics was won by Albert Einstein for his work in the field of theoretical physics.
-
The force of gravity 100 kilometres (62 miles) above Earth is just 3% less than at the Earth’s surface
- Lightning is a discharge of electricity in the atmosphere. Lightning bolts can travel at around 210,000 kph (130,000 mph), while reaching nearly 30,000 °C (54,000 °F) in temperature.
- Energy can be transformed from one form to another. In lightning, electric potential energy transforms into light, heat and sound energy.
- When traveling through water, sound moves around four times faster than when it travels through air.
- One of the many things Italian scientist Galileo Galilei worked on was telescopes, producing telescopes with around 30x magnification in some of his later work. These telescopes helped him discover the four largest moons orbiting Jupiter (later named the Galilean satellites).
