Front

What is the attractive force that exists between all objects that have mass?

Back

Gravity is the attractive force that exists between all objects that have mass.

Front

What happens when two boys pull with the same amount of force?

Back

They will not move at all.

Front

What is a PUSH or PULL of an object called?

Back

A PUSH or PULL of an object is called Force.

Front

What is Newton's First Law?

Back

Newton's First Law states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What does the Law of Inertia (1st law) explain?

Back

The Law of Inertia explains that an object will remain at rest or in uniform motion unless acted upon by an external force.

Front

What is the formula for Newton's Second Law?

Back

The formula for Newton's Second Law is F=ma, where F is force, m is mass, and a is acceleration.

Front

What does Newton's Third Law state?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object in contact with another surface.

Front

What is an example of gravitational force?

Back

An example of gravitational force is the attraction between the Earth and an apple falling from a tree.
