Newton's Third Law

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is an opposing force?

Back

A force in an opposite direction with the same strength.

Front

Do action and reaction forces cancel each other out?

Back

No, they do not cancel out because they act on different objects.

Front

When you push on a wall, what happens?

Back

The wall pushes back on you with equal force.

Front

If a rock weighs 40 N, how much force does the ground exert on it?

Back

40 N.

Front

What happens to the forces when two objects collide?

Back

The forces are equal and act on different objects.

Front

What is an example of action and reaction forces?

Back

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

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

Acceleration is inversely proportional to mass when force is constant.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational force.
