What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate because the forces acting on it are not equal.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

What does Newton's First Law of Motion state?

Back

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

Front

What does Newton's Second Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).
