Physics Exam review

Front

What does the area under a v/t graph tell us?

Back

The displacement.

Front

What is the formula for calculating slope?

Back

Slope = (change in y) / (change in x).

Front

How do you calculate time if distance and speed are known?

Back

Time = Distance / Speed.

Front

What is the unit of speed?

Back

Meters per second (m/s).

Front

What does a negative slope indicate in a v/t graph?

Back

The object is decelerating.

Front

What is the formula for position in linear motion?

Back

Position = (initial position) + (velocity)(time).

Front

What does a flat line on a v/t graph represent?

Back

Constant velocity.

Front

How do you find the velocity from a position vs. time graph?

Back

The slope of the position vs. time graph.

Front

What is the significance of the y-intercept in a position vs. time graph?

Back

It represents the initial position of the object.

Front

What is the relationship between speed and velocity?

Back

Speed is a scalar quantity; velocity is a vector quantity.
