In these revision notes for Kinetic Energy, we cover the following key points:
Kinetic Energy is the energy of a moving object. This means when an object is at rest it does not possess Kinetic Energy.
Kinetic Energy is denoted in equations as KE. As all the other types of energy, it is also measured in Joules [J].
Kinetic Energy of a moving object depends on two factors:
The equation that relates Kinetic Energy with the abovementioned factors is
The Work-Kinetic Energy Theorem, states that
"The work done by the sum of all forces acting on an object equals the change in the kinetic energy of the object itself."
Mathematically, the Work-Kinetic Energy Theorem is written as:
