Newtons Laws of Motion

Front

What is Newton's First Law?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Why are the forces on a squirrel sitting on the ground balanced?

Back

The squirrel is not accelerating.

Front

Why is it harder to push a van filled with bowling balls than one filled with basketballs?

Back

The mass of the bowling balls is greater than the mass of the basketballs.

Front

Which law corresponds to the equation F=ma?

Back

Newton's second law of motion.

Front

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

Back

They will not move at all.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for Newton's Second Law?

Back

F = ma (Force = mass × acceleration).

Front

What does Newton's Third Law state?

Back

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

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.
