Week 16 - Potential and Kinetic Energy

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

How can you increase an object's gravitational potential energy?

Back

By lifting the object higher in a gravitational field.

Front

What are examples of chemical potential energy?

Back

Wood, batteries, gasoline, and food are all examples of chemical potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, which depends on its mass and velocity.

Front

How does speed affect kinetic energy?

Back

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

Front

What is the formula for kinetic energy?

Back

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

Front

What happens to kinetic energy if the mass of an object is doubled while keeping the speed constant?

Back

The kinetic energy will also double.

Front

What is the relationship between mass and gravitational potential energy?

Back

Gravitational potential energy increases with an increase in mass, given a constant height.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is an example of a situation with high potential energy?

Back

A book on a high shelf has high gravitational potential energy due to its height.
