period 8 - Forces Review

Front

What is the Law of Inertia?

Back

The Law of Inertia states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is an action-reaction pair?

Back

An action-reaction pair refers to two forces that are equal in size, but opposite in direction, acting on two different objects.

Front

What does it mean when we say forces are equal and opposite?

Back

It means that when one object exerts a force on another, the second object exerts a force of equal strength in the opposite direction back on the first object.

Front

What is an example of action and reaction in everyday life?

Back

When you jump off a diving board, you push down on the board (action), and the board pushes you up into the air (reaction).

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, occurring when two surfaces come into contact.

Front

How does gravity affect objects?

Back

Gravity is a force that attracts two bodies toward each other, causing objects to fall towards the Earth.

Front

What happens when a bat hits a ball?

Back

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

Front

What is the reaction force when a swimmer pushes water backward?

Back

The reaction force is that the swimmer moves forward as a result of pushing the water backward.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What is an example of gravity in action?

Back

An example of gravity in action is an apple falling from a tree to the ground.
