Applying Newton's Third Law Flashcard

Front

What is Newton's Third Law of Motion?

Back

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

Front

How does a rocket propel itself in space?

Back

A rocket propels itself by expelling exhaust gases backward, which pushes the rocket forward.

Front

What is the reaction force when a book rests on a table?

Back

The normal force exerted by the table on the book.

Front

What happens when an astronaut throws an object in space?

Back

The astronaut will move in the opposite direction of the thrown object due to Newton's Third Law.

Front

Why do rockets work in the vacuum of space?

Back

Rockets work in space because they expel gases, creating thrust, even without air.

Front

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

Back

When a basketball player jumps, the action is pushing down on the ground, and the reaction is the ground pushing the player upwards.

Front

What is the role of air resistance in motion?

Back

Air resistance opposes the motion of objects moving through the air.

Front

How does gravity affect objects in free fall?

Back

Gravity pulls objects towards the Earth, causing them to accelerate downwards.

Front

What is the normal force?

Back

The normal force is the support force exerted by a surface perpendicular to the object resting on it.

Front

What is an example of action-reaction forces in everyday life?

Back

When you sit in a chair, your body exerts a downward force on the chair, and the chair exerts an upward force on your body.
