period 9 - Forces Review

Front

What is Newton's Third Law of Motion?

Back

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

Front

Define force.

Back

A push or pull on an object resulting from the object's interaction with another object.

Front

What is gravity?

Back

A force that attracts two bodies toward each other, commonly experienced as the force that pulls objects toward the Earth.

Front

What happens to a rocket when it expels exhaust gases?

Back

The rocket moves upward due to the downward force of the exhaust gases, demonstrating Newton's Third Law.

Front

What is an action-reaction pair?

Back

Two forces that are equal in size, opposite in direction, and act on different objects.

Front

What is the role of air resistance when a bird flies?

Back

Air resistance acts against the motion of the bird, affecting its speed and direction.

Front

What is the net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How does a bat hitting a baseball illustrate Newton's Third Law?

Back

The bat exerts a force on the ball, and the ball exerts an equal and opposite force back on the bat.

Front

What is inertia?

Back

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

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant speed.
