Identifying Newton's 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 with the same speed and in the same direction unless acted upon by an unbalanced 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. This is often expressed as the formula F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

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

Back

For a given force, an increase in mass results in a decrease in acceleration.

Front

What happens to a moving object in space when no forces act on it?

Back

It will continue to move in a straight line at a constant speed indefinitely.

Front

What is inertia?

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

Front

How does Newton's 2nd Law apply to sports?

Back

A lighter ball will accelerate more than a heavier ball when the same force is applied.

Front

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

Back

Force equals mass times acceleration (F = ma).

Front

Explain the concept of action and reaction forces with an example.

Back

When you jump off a small boat, you push the boat backward (action), and the boat pushes you forward (reaction).
