Newton's Three Laws Review

Front

What is Newton's 1st Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is another name for Newton's 1st Law?

Back

The Law of Inertia.

Front

What does Newton's 2nd Law of Motion state?

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 Newton's 3rd Law of Motion?

Back

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

How does Newton's 1st Law apply to a pencil left on a desk?

Back

The pencil remains at rest until acted upon by an external force (e.g., someone picking it up).

Front

What happens to the energy of a ball when it strikes a wall?

Back

The energy is not destroyed; it is transformed, and the forces between the ball and the wall are equal and opposite.

Front

What is the relationship between action and reaction forces according to Newton's 3rd Law?

Back

Action and reaction forces are equal in magnitude and opposite in direction.

Front

How can you identify an unbalanced force in a scenario?

Back

An unbalanced force can be identified when an object changes its state of motion (speeding up, slowing down, or changing direction).

Front

What is the formula for calculating force in Newton's 2nd Law?

Back

Force (F) = mass (m) × acceleration (a).

Front

Give an example of Newton's 2nd Law in action.

Back

A car accelerates faster when a greater force is applied (e.g., pressing the gas pedal harder).
