Potential vs. Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that has the potential to do work.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the square of its velocity.

Front

If the speed of a roller coaster cart doubles, the kinetic energy ___________.

Back

quadruples

Front

True or False: The amount of material affects the amount of energy that an object has.

Back

TRUE

Front

Which ball has the most potential energy? A ball held at 3 meters, 2 meters, 1 meter, or a ball resting on the ground?

Back

A ball held at 3 meters.

Front

What describes the relationship between kinetic energy and an object's mass?

Back

Linear

Front

Mass and height are _____ proportional to potential energy.

Back

directly

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

What happens to potential energy when an object is lifted higher?

Back

The potential energy increases as the height of the object increases.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mass (m) * gravity (g) * height (h).
