Front

What is Newton's 1st Law of Motion?

Back

An object will not change its motion unless an unbalanced force acts on it.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is mass?

Back

Mass is the amount of matter in an object, measured in kilograms (kg). It does not change regardless of location.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur due to a change in speed or direction.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal, causing a change in the motion of an object.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).
