Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

Where is potential energy highest in a roller coaster?

Back

At the top of a big hill.

Front

How does speed affect kinetic energy?

Back

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

Front

What type of energy does an acorn hanging from a tree have?

Back

Potential Energy.

Front

What type of energy does a rock at the edge of a cliff have?

Back

Potential Energy.

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 formula for calculating kinetic energy?

Back

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

Front

What is gravitational potential energy?

Back

Gravitational Potential Energy is the potential energy held by an object because of its height above the ground.

Front

At which point in a roller coaster is kinetic energy greatest?

Back

At the bottom of a hill.
