Kinetic & Potential Energy Review

Front

What is energy?

Back

Energy is the ability to cause change.

Front

What happens when you do work?

Back

When you do work, you are exerting energy.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How does potential energy change during a descent?

Back

Potential energy decreases as it is converted to kinetic energy.

Front

What factors affect kinetic energy?

Back

Kinetic energy depends on the mass and speed of an object.

Front

If two objects are moving at the same speed, how do you determine which has more kinetic energy?

Back

The object with greater mass has more kinetic energy.

Front

What happens to energy in a pendulum as it swings?

Back

As a pendulum swings, potential energy decreases while kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

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