Forces and Newton's Laws

Front

What is Newton's Third Law of Motion?

Back

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

Front

What force opposes the motion of an object?

Back

Friction.

Front

How is momentum calculated?

Back

Momentum = mass × velocity.

Front

What factors affect the amount of friction between two surfaces?

Back

The types of surfaces and the force pressing them together.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

Force = mass × acceleration.

Front

What happens to an object at rest according to Newton's First Law?

Back

An object at rest tends to stay at rest unless acted upon by a net external force.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating the net force acting on an object?

Back

Net Force = mass × acceleration.
