DOL: Kinetic & Potential Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. It is the energy an object possesses due to its movement.

Front

What is potential energy?

Back

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

Front

How does speed affect kinetic energy?

Back

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

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

At which point in a pendulum's swing is kinetic energy greatest?

Back

Kinetic energy is greatest at the lowest point of the swing.

Front

At which point in a pendulum's swing is potential energy greatest?

Back

Potential energy is greatest at the highest points of the swing.

Front

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

Back

A rock at the edge of a cliff possesses potential energy.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What happens to kinetic energy when an object comes to a stop?

Back

When an object comes to a stop, its kinetic energy is converted to other forms of energy, such as heat.
