Unit 3 Review: Newton's Laws and Force in One Dimension

Front

What happens when two boys pull with the same amount of force?

Back

Neither will move.

Front

What is the formula to calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If an object accelerates at 2 m/s² from rest, how long does it take to reach 16 m/s?

Back

8 seconds.

Front

Define inertia.

Back

The tendency of an object to resist changes in velocity.

Front

What is the formula to calculate force?

Back

Force = Mass x Acceleration.

Front

What force is required to accelerate a 60 kg cart at 2.0 m/s²?

Back

120.0 N.

Front

What does a constant positive velocity graph look like?

Back

A straight line with a positive slope.

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 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 is Newton's Third Law of Motion?

Back

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