Newton's 1st Law

Front

What does Newton's 1st Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is inertia?

Back

The tendency of an object to resist a change in its motion.

Front

What is an unbalanced force?

Back

A force that causes a change in the motion of an object.

Front

What happens to a moving object if no unbalanced force acts on it?

Back

It will remain in motion.

Front

What is the net force when 8 N is applied to the left and 4 N to the right?

Back

4 N to the left.

Front

Are balanced forces able to change an object's motion?

Back

No, balanced forces do not change an object's motion.

Front

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

Back

A magician pulling a tablecloth from under dishes without moving them.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating net force?

Back

Net Force = Force applied - Force opposing.

Front

What is the effect of gravity on an object's motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion.
