jump and bounce
When jumping, for example, a person pushes the ground with his foot backwards, so he pushes forward or higher. This is from the rebound, and it is known in physics and kinesiology.in english (recoil) Backlash that occurs, for example, to the cannon when the projectile is launched, or the backlash of the gun when the bullet is fired, and the direction of movement is opposite to the direction of the launch and acceleration of the projectile.
This phenomenon occurs in our daily life a lot, as every action has a reaction equal in magnitude and opposite in direction..
Weight and mass vary greatly even though the words are used interchangeably in the English language.
Language: mass is a measure of the total amount of matter or matter that an object is made of.
Mass is measured in kilograms.
Weight is a measure of the amount of force an object pulls on and is measured in newtons (N).
Weight depends on mass, acceleration, or gravity“.
The mathematical relationship can be described by the following equation:
W =m x c (n)
letter . varies “g” Denotes acceleration depending on the planet you’re standing on.
In general, the planets with the largest mass have the strongest attraction to the surface.
(on the surface of the ground g = 9.8kg / m / s2(
Where m = Meter
If your mass is 70 kg, then weight = 70 x 9.8 = 686 newtons.
So your weight can vary depending on which planet you are on, but your mass remains the same.
Planets in our solar system, Pluto (a dwarf planet) and the Moon.
With this information they can calculate and compare jump heights and read pigeon scales (calibrated to the ground) if they would be standing on different objects in the solar system.
The higher the surface gravitational force, the more they are attracted by the planet, moon or star, making it more difficult for them to jump.
