Newton's Laws of Motion Review

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 an external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to mass.

Front

What happens to a ball of cheese fired into frictionless space?

Back

It will continue moving indefinitely without any additional force acting on it.

Front

What unit is force measured in?

Back

Newtons (N) is the unit of force in the International System of Units (SI).

Front

What does Newton's Third Law state?

Back

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

Front

If an object has twice the mass of another, what can be said about its inertia?

Back

The object with twice the mass has twice the inertia.

Front

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

Back

Force equals mass times acceleration (F=ma).

Front

What is an example of Newton's First Law in everyday life?

Back

A book resting on a table will remain at rest until someone pushes it.

Front

How does friction affect motion according to Newton's laws?

Back

Friction is a force that opposes motion, affecting how objects move according to Newton's laws.

Front

What is the effect of a large truck pushing a small car?

Back

The small car applies an equal and opposite force on the truck, demonstrating Newton's Third Law.
