Newton's Laws

Front

What is Newton’s first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the difference between speed and velocity?

Back

Velocity includes direction, while speed does not.

Front

When does a change in motion occur?

Back

A change in motion occurs when the forces acting on an object are unbalanced.

Front

What is the formula to calculate acceleration?

Back

Acceleration = Net Force / Mass.

Front

If you exert a net force of 8 N on a 2-kg object, what is its acceleration?

Back

4 m/s².

Front

What is an example of velocity?

Back

25 m/s East.

Front

What is Newton’s second law of motion?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces mean that the total net force acting on an object is zero, resulting in no change in motion.

Front

What is an example of an unbalanced force?

Back

A person pushing a stationary car to get it moving.

Front

What is the unit of force?

Back

Newton (N).
