You serve a volleyball with a mass of 2.1 kg. The ball leaves your hand with a speed of 30 m/s. What is the kinetic energy of the ball?
The answer is 945 Joules. 1/2 of 2.1 x 302 = 945.
The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity. However, mass and velocity are indirectly related. Objects with greater mass can have more kinetic energy even if they are moving more slowly, and objects moving at much greater speeds can have more kinetic energy even if they have less mass. We must consider both the speed and mass of objects when considering the outcomes of collisions.

A monster truck is traveling at 100 meters per second and runs straight into a bike (with no one on it) The bike is traveling towards the truck at 5 meters per second. As expected, the bike goes flying because it has less kinetic energy than the monster truck. How fast would the bike have to be going to make the monster truck go flying instead?

Would a ball have more gravitational potential energy when it is kicked in the air, or when it's on the ground?
Would a ball have more gravitational potential energy when it is kicked in the air, or when it's on the ground?
The answer is "when it is in the air" because when objects are positioned higher off the ground they have more gravitational potential energy.
Potential Energy is “stored energy.” It is energy that is ready to be converted or released as another type of energy. We most often think of potential energy as gravitational potential energy. When objects are higher up, they are ready to fall back down. When you stretch an object and it has a tendency to return to its original shape, it is said to have elastic potential energy. Chemical potential energy is the stored energy in a substance’s chemical structure that can be released in a chemical reaction or as heat.
Potential energy is greatest when the most energy is stored. This could be when an object reaches its highest point in the air before falling, a rollercoaster just before it drops, or when a rubber band is stretched as far back as possible before it snaps. Potential energy is then converted to kinetic energy.
