Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant speed and in a straight line unless acted upon by an unbalanced force.

Front

Define inertia.

Back

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

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 (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the unit of force?

Back

Newton (N).

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

Give 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

What happens to an object in motion when no external forces act on it?

Back

It will continue to move at a constant velocity.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F=ma).
