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. For example, a stretched bungee cord has elastic potential energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its position in a gravitational field. It is calculated based on the object's height above the ground.

Front

What is the normal force?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is the relationship between action and reaction forces?

Back

According to Newton's third law, for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What happens when you jump on a trampoline?

Back

When you jump on a trampoline, you apply a downward force, and the trampoline exerts an equal and opposite force back up, allowing you to bounce.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 times the mass of the object times the velocity squared.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, which can be released during a chemical reaction.

Front

What is an example of a force?

Back

An example of a force is the push or pull exerted by a person or object, such as pushing a door open.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects towards the center of the Earth, giving them weight and causing them to fall when dropped.
