KInetic and Potential Energy Modified

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The stored energy of an object due to its position or condition.

Front

How does potential energy change as an object falls?

Back

The potential energy decreases as the kinetic energy increases.

Front

What happens to kinetic energy when an object's speed doubles?

Back

The kinetic energy increases by a factor of four.

Front

What is the formula for kinetic energy?

Back

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

Front

What is the formula for potential energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What type of energy does a stretched spring have?

Back

Potential energy, specifically elastic potential energy.

Front

What is gravitational potential energy?

Back

The potential energy an object has due to its height above the ground.

Front

How do you increase the potential energy of an object?

Back

By increasing its height or mass.

Front

What is the relationship between kinetic and potential energy in a closed system?

Back

They convert into each other, maintaining the total mechanical energy constant.
