Newton's First Law of Motion

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is a force?

Back

A push or pull exerted on an object.

Front

What happens to an object if the net force acting on it is zero?

Back

The object will not change its state of motion; it will remain at rest or continue moving at a constant velocity.

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

Forces that are not equal and opposite, causing a change in the motion of an object.

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

Back

It means the object is changing its position relative to a reference point.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it is harder to change its motion.
