Energyizing Everything Lesson Assessment 4&5

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object has due to its height above the ground. The higher an object is, the more gravitational potential energy it has.

Front

What happens to height energy when an object falls?

Back

When an object falls, its gravitational potential energy is converted into kinetic energy, which is the energy of motion.

Front

How can you increase the energy of a marble in a ramp system?

Back

You can increase the energy of a marble by making the ramp taller, which gives the marble more height energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is the relationship between height energy and motion energy?

Back

Height energy (gravitational potential energy) can be converted into motion energy (kinetic energy) when an object moves down a ramp.

Front

What is an example of a machine that uses gravitational potential energy?

Back

A roller coaster uses gravitational potential energy when it climbs to the top of a hill and then converts that energy into kinetic energy as it descends.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula is: Gravitational Potential Energy (GPE) = mass (m) × gravity (g) × height (h).

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

Front

How does the height of a ramp affect the speed of a marble at the bottom?

Back

A taller ramp gives the marble more gravitational potential energy, which converts to more kinetic energy, making the marble go faster at the bottom.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in objects that can be stretched or compressed, like springs or rubber bands.
