AKS 8b/8c Review

Front

What happens to objects falling in a vacuum?

Back

All objects fall at the same rate regardless of their mass.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What force opposes the motion of falling objects?

Back

Air Resistance.

Front

How do you calculate the weight of an object near Earth's surface?

Back

Weight = mass (m) x acceleration due to gravity (g).

Front

What happens to the acceleration of an object when the net force is doubled?

Back

The acceleration doubles.

Front

What is the formula for calculating force?

Back

Force = mass (m) x acceleration (a).

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

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.

Front

What is an example of Newton's 1st Law of Motion?

Back

An object at rest stays at rest unless acted upon by a net external force.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance slows down the acceleration of falling objects.
