Semester Exam Review Physics

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 formula for calculating force?

Back

F = ma (Force equals mass times acceleration).

Front

What are the units for measuring speed?

Back

Meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does a flat line on a distance-time graph indicate?

Back

The object is at rest.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

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 the slope of a distance-time graph represent?

Back

The speed of the object.

Front

What is the definition of acceleration?

Back

Acceleration is the rate of change of velocity per unit time.
