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 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. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What unit is used to measure force?

Back

Newtons (N) are the units used to measure force.

Front

What does inertia refer to in Newton's 1st Law?

Back

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

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

Can you give an example of Newton's 3rd Law?

Back

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

Front

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

Back

Force equals mass times acceleration (F = ma).

Front

What is an unbalanced force?

Back

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

Front

What happens to a moving skateboard when a person steps on it?

Back

The skateboard stops due to the unbalanced force applied by the person's weight.
