Kinetic energy is the energy of motion, and is defined as mass times velocity. Evidence of kinetic energy include Examples of:
Orbital motion: moons about the planets, or the planets around the sun. The motion of the stars in a galaxy, orbiting satellites and space vehicles.
Random linear motion: On a molecular level, vibrations of molecules, gas molecules bouncing around a room.
Rotational or torquing motion: spinning flywheels, rolling balls or wheels
Projectile (parabolic) motion: a fired bullet, a thrown ball, a boy jumping
Linear motion: running, bowling, aircraft in flight, a moving car or train, a boy skateboarding
