Newtons First Law

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 at a constant velocity unless acted upon by an unbalanced force.

Front

What is an unbalanced force?

Back

A force that causes a change in the motion of an object, resulting in acceleration or deceleration.

Front

What is a balanced force?

Back

Equal forces acting in opposite directions that do not cause a change in an object's motion.

Front

What is friction?

Back

The unbalanced force that opposes the motion of an object.

Front

What unit is used to measure force?

Back

Newton (N).

Front

What happens when two equal forces act in the same direction?

Back

They create a balanced force, resulting in no change in motion.

Front

What happens when two unequal forces act in opposite directions?

Back

They create an unbalanced force, resulting in a change in motion.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and inertia?

Back

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

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.
