Newton's 3rd Law

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is an action force?

Back

The force exerted by one object on another.

Front

What is a reaction force?

Back

The force exerted by the second object back on the first object.

Front

Give an example of Newton's 3rd Law in action.

Back

When a swimmer pushes the water backwards, the water pushes the swimmer forward.

Front

What happens to the forces when a cannon fires a cannonball?

Back

The cannon exerts a force on the cannonball, and the cannonball exerts an equal and opposite force on the cannon.

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

Acceleration is inversely proportional to mass when the same force is applied.

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate because the forces acting on it are not equal.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

How does mass affect acceleration when a force is applied?

Back

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

Front

What is inertia?

Back

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