Newtons Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What does 'inertia' mean?

Back

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

Front

What is an example of Newton's 1st Law?

Back

A ball rolling on the ground will keep rolling until friction or another force stops it.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma).

Front

What is an example of Newton's 2nd Law?

Back

If you push a car and a bicycle with the same force, the bicycle will accelerate faster because it has less mass.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is an example of Newton's 3rd Law?

Back

When you jump off a small boat, the boat moves backward as you move forward.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What happens to an object at rest when no forces act on it?

Back

It stays at rest due to inertia.

Front

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

Back

It continues to move at a constant speed in a straight line due to inertia.
