Front

What is a chemical change?

Back

A process where substances combine or break apart to form new substances, often accompanied by energy changes, color changes, gas production, or temperature changes.

Front

Which is NOT evidence of a chemical change?

Back

Breaking an object is a physical change, not a chemical change.

Front

What is density?

Back

Density is the mass of an object divided by its volume, indicating how much matter is packed into a given space.

Front

If two objects have the same volume but different masses, which one is more dense?

Back

The object with more mass is more dense.

Front

What is potential energy?

Back

Potential energy is stored energy in an object due to its position or state, such as a stretched spring or an object at height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and speed.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in an object when it is stretched or compressed, like in a spring.

Front

In which position does a spring have the least elastic potential energy?

Back

When the spring is in its natural, uncompressed state.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What does it mean when an object is in motion?

Back

An object in motion will stay in motion unless acted upon by an outside force.
