Front

What happens when two forces of equal magnitude act in opposite directions?

Back

Front

What are the two types of forces that can act on an object?

Back

Push and pull.

Front

What is the definition of friction?

Back

Friction is the force that slows and stops motion between touching objects.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What is the effect of increasing the mass of an object on the force required to move it?

Back

Increasing the mass of an object increases the force required to move it.
