Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the reaction force when a cannon fires a cannonball?

Back

The cannon moving backward.

Front

What does Newton's Law of F=ma state?

Back

The force acting on an object is equal to the mass of that object multiplied by its acceleration.

Front

If a bowling ball requires more force to accelerate than a tennis ball, which law explains this?

Back

Newton's Law of F=ma.

Front

What is the formula to calculate mass using force and acceleration?

Back

Mass = Force / Acceleration.

Front

If a force of 560 N produces an acceleration of 20 m/s², what is the mass?

Back

28 kg.

Front

What happens to the net force when forces on an object are unbalanced?

Back

The net force is any positive/negative number but not zero.

Front

What is acceleration?

Back

The rate at which velocity changes.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
