Kinetic energy is mainly based on ___
velocity
Is kinetic energy linear or non-linear
non-linear
Kinetic energy: Forces add ___ by changing the ____
Forces add energy by changing the speed
Kinetic energy is the energy of what
motion
If two objects have the same mass but one has more velocity are they the same?
No, the one with more velocity has more energy
If a small object and a large object have the same amount of energy, how is that possible
The small object has a high velocity
what is energy
