Front

What law of motion states that for every action, there is an equal and opposite reaction?

Back

Newton's 3rd law

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 formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What is inertia?

Back

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

Front

What is gravitational force?

Back

The attractive force between two objects due to their mass.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
