Back

Potential Energy

Front

What type of energy is associated with an object's motion?

Back

Kinetic Energy

Front

What is the unit of measurement for height?

Back

meters (m)

Front

What is the first step in calculating kinetic energy?

Back

Square the velocity.

Front

What is the formula for calculating potential energy?

Back

Potential Energy = mass × gravity × height (PE = mgh)

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy = ½ × mass × velocity² (KE = ½ mv²)

Front

What does kinetic energy depend on?

Back

Kinetic energy depends on the mass of the object and the square of its velocity.

Front

What does potential energy depend on?

Back

Potential energy depends on the mass of the object, the height above the ground, and the acceleration due to gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².
