What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in the motion of an object.

What happens to objects in motion according to Newton's First Law?

Back

Objects in motion tend to stay in motion unless acted upon by an unbalanced force.

Front

What is the opposite reaction in Newton's Third Law?

Back

For every action, there is an equal and opposite reaction.

What is inertia?

Back

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

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air.
