Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It is often associated with gravitational potential energy, which depends on an object's height above the ground.

Front

What type of energy does a moving skateboard have?

Back

Kinetic Energy.

Front

At what point does a diver have the greatest kinetic energy during a dive?

Back

At the lowest point of the dive, just before entering the water.

Front

Where is gravitational potential energy the least?

Back

At the lowest point, such as down in the basement.

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

If a baseball has a mass of 0.145 kg and is thrown at a velocity of 30.0 m/s, what is its kinetic energy?

Back

65.25 J.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between kinetic energy and mass?

Back

Kinetic energy is directly proportional to the mass of the object; if mass increases, kinetic energy increases if velocity remains constant.
