Front

When forces acting on an object are balanced, what happens to the object's motion?

Back

The object's motion remains unchanged.

What force is responsible for slowing down a rolling ball on the ground?

Back

Friction is the force that slows down a rolling ball.

Front

Which law of motion describes an object's resistance to a change in its motion?

Back

Newton's 1st Law describes an object's resistance to change in motion.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is the role of friction in motion?

Back

Friction opposes the motion of objects and can cause them to slow down or stop.

Front

How does mass affect the acceleration of an object?

Back

Greater mass results in less acceleration for the same amount of force applied.
