The wall pushes on you with a force of 30 N.
The wall moves back 3 cm.
The wall cannot be forced.
You are pulled towards the wall.
The car pushes back on you, gravity pulls you down, the ground pushes up on you, and friction on your shoes pushes forward on you.
Only gravity.
Your own muscles push you down.
No forces act on you.
The person has more kinetic energy before they jump than after they jump.
The person has less potential energy at the top of the platform than in the air.
The person's potential energy at the instant they jump is approximately equal to their kinetic energy the instant they land.
The person's kinetic energy at the instant they jump is approximately double their potential energy the instant they land.
The work done on the object to put the object into its current state.
The velocity of the object divided by its mass.
The force of gravity working on the object.
The size of the object compared to its surface area.
Double the velocity of the object
Double the mass of the object
Double the potential energy
Double the temperature of the object
The rate at which work is done
The energy necessary to do work
The velocity of an object squared
The sum of potential and kinetic energy
The square root of 2gh
One-half the mass squared
Two times ghm squared
H-2gm
Potential Energy can never be greater than Kinetic Energy
The energy in a closed system is always constant
The Kinetic Energy of a dropped object at the instant it hits the ground is roughly equal to the potential energy of the object at the instant it was dropped
It is not necessary to use Kinematics to discover the velocity of an object accelerated by gravity if you know it's initial Potential Energy and its mass.
The object's Potential Energy is increasing.
The object's Kinetic Energy is decreasing.
The object's Kinetic Energy is constant.
The object's speed is constant.
