Newtons laws

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What is Newton's 2nd 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 3rd Law of Motion?

Back

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

Front

Why should motorists buckle up according to Newton's 1st Law?

Back

Because if the car stops suddenly, the body will continue moving forward due to inertia.

Front

What does inertia mean?

Back

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

Front

Give an example of Newton's 1st Law in everyday life.

Back

A soccer ball will not move until someone kicks it.

Front

What is the formula for Newton's 2nd Law?

Back

F = ma (Force equals mass times acceleration).

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

The greater the mass of an object, the less acceleration it will have for a given force.

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 happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.
