Newton's 1st Law of Motion

Front

What is Newton's First Law known as?

Back

The Law of Inertia.

Front

Speed in a certain direction is known as:

Back

Velocity.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted on by another force.

Front

If unbalanced forces act on an object at rest, what happens to the object?

Back

It will move.

Front

What is inertia?

Back

An object's tendency to stay in motion or to stay at rest.

Front

What does it mean for an object to be in motion?

Back

It means the object is changing its position over time.

Front

What is an example of inertia in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What happens to an object in motion if no forces act on it?

Back

It continues to move at a constant velocity.

Front

What is the relationship between mass and inertia?

Back

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

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.
