Newtons Laws Review

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the net force when multiple forces act on an object?

Back

The net force is the overall force acting on an object after all the individual forces are combined.

Front

What happens to the forces acting on a marble rolling down a ramp?

Back

The forces are unbalanced, causing the marble to accelerate.

Front

What term describes the amount of matter in an object?

Back

Mass.

Front

How do you calculate force using mass and acceleration?

Back

Force (F) = Mass (m) × Acceleration (a).

Front

If a 10 kg object accelerates at 15 m/s², what is the force applied?

Back

150 Newtons.

Front

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

Back

Newton (N).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is an example of balanced forces?

Back

A book resting on a table, where the force of gravity is balanced by the normal force from the table.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in motion, such as acceleration or deceleration.
