FORCES AND MOTION

Match correctly:

• Newton's second law

• States that inertia is proportional to mass.

• Newton's third law

• States that force = mass x acceleration.

• Newton's first law

• States that every force of action has an equal and opposite reaction.

Match each situation with the correct Newton's law of motion:

• Newton's first law

• Reducing the weight of race cars to increase their speed.

• Newton's second law

• When you turn off a fan, the blades continue to move for a while, even without electricity.

• Newton's third law

• The rocket expels gases downward, which causes the rocket to move upward and launch.
