Front

What is Newton's First Law of Motion?

Back

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

Front

What happens when two ice skaters push off each other?

Back

The skater with the greater mass will cause the other skater to move farther away.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

What does a free-body diagram represent?

Back

A free-body diagram shows all the forces acting on an object.

Front

What is net force?

Back

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

Front

How does mass affect acceleration according to Newton's Second Law?

Back

The greater the mass of an object, the less acceleration it will have when a given force is applied.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a)
