Sir Isaac Newtons First Law of Motion Flashcard

Front

What is acceleration?

Back

Acceleration is best described as a change in an object's velocity.

Front

What is an example of a contact force?

Back

Friction is always a contact force.

Front

How do you calculate net force when two forces are acting in the same direction?

Back

You add the forces together.

Front

What is Newton's 1st Law of Motion also called?

Back

Newton's 1st Law is also called the Law of Inertia.

Front

What does the term 'net force' refer to?

Back

Net force refers to the overall force acting on an object when all the individual forces are combined.

Front

What happens to an object at rest according to Newton's 1st Law?

Back

An object at rest will stay at rest unless acted upon by an unbalanced force.

Front

What happens to an object in motion according to Newton's 1st Law?

Back

An object in motion will continue in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is inertia?

Back

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

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If two forces of 3 N and 3 N are acting in the same direction, what is the net force?

Back

The net force is 6 N.
