What is the kinetic energy of a 1 kg ball that is thrown into the air with an initial velocity of 30m/s?

How is velocity different than speed? - Velocity is how fast something is moving at one specific moment. Example: you can run on a treadmill at 10 mph. -Velocity is speed with direction. Example: you can run outside at 10 mph north.
