Question

kinetic energy causes speed or speed causes kinetic energy??? which is correct??

Answer 1

The kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Answer 2

When they collide at a high rate of speed, their kinetic energies collide causing a lot of damage. So changing kinetic energy can happen two ways: 1. When an object has more or less mass, it can change its kinetic energy.
