What describes an object's motion that has changed speed and/or direction?

Back

Unbalanced.

Front

What is another name for the first Law of Motion?

Back

Law of Inertia.

Front

What is Newton's Second Law?

Back

F=ma.

Front

What is the definition of balanced forces?

Back

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

Front

What is the definition of unbalanced forces?

Back

Forces that cause a change in motion because they are not equal and opposite.

Front

What does Newton's First Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F=ma).
