Newton's 3rd Law: Action-Reaction

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Define action force in the context of Newton's 3rd Law.

Back

The force exerted by one object on another.

Front

Define reaction force in the context of Newton's 3rd Law.

Back

The force exerted by the second object back on the first object, equal in magnitude and opposite in direction.

Front

If a book exerts a downward force of 20 N on a table, what is the reaction force?

Back

The table exerts an upward force of 20 N on the book.

Front

What happens to the acceleration of an object when a greater force is applied?

Back

The acceleration of the object increases.

Front

In a collision between a small object and a large object, which experiences greater acceleration?

Back

The smaller object experiences greater acceleration.

Front

What is an example of action-reaction forces in sports?

Back

When a player pushes off the ground to jump, the ground pushes back with an equal and opposite force.

Front

If a person pushes against a wall with a force of 50 N, how much force does the wall exert back?

Back

The wall exerts a force of 50 N back on the person.

Front

What is the relationship between action and reaction forces?

Back

They are equal in magnitude and opposite in direction.

Front

Describe a real-life example of Newton's 3rd Law of Motion.

Back

When a rocket launches, the engines push down on the ground (action), and the ground pushes the rocket upward (reaction).
