Term1/14
What is kinetic energy
Definition1/14

Kinetic energy is the energy that an object has due to its motion or movement. For instance if a car drives into a wall the energy of its movement is what destroys the wall, That energy is kinetic energy.

Note: Heat is also a form of Kinetic energy because heat is the movement (vibration energy) of atoms or molecules.

When the mover pushes the box up the ramp there is friction between the box and the ramp What is the efficiency of the ramp
Definition1/14

It depends on the mass of the box, the force exerted, the total displacement and the height the box was moved.

Does speed affect gravitational potential energy of an object
Definition1/14

Does speed 'effect' the gravitational potential energy of an object? No, but gravitational potential energy can be converted into kinetic energy - so the gravitational potential energy can effect the speed.

Ep = mgh

Energy Potential = mass * 9.81 (gravity) * height

Speed / Velocity is absent from that equation.
