Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls us toward the Earth.

Front

What tool would you use to measure the mass of an object?

Back

A balance or scale.

Front

What is the unit of force?

Back

Newton (N) is the unit used to measure force.

Front

What happens to an object when a force is applied?

Back

The object's motion can change; it can start moving, stop moving, or change direction.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the greater the gravitational force it experiences.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is a spring scale used for?

Back

A spring scale is used to measure the weight or force of an object.

Front

If two objects have the same mass, which will fall faster?

Back

They will fall at the same rate if air resistance is negligible.

Front

What is the effect of height on falling objects?

Back

Objects dropped from greater heights have more time to accelerate due to gravity.
