Speed and Velocity Unit 1 Study Guide

Front

What is speed?

Back

Speed is the rate at which an object covers distance. It is a scalar quantity, meaning it only has magnitude and no direction.

Front

What is velocity?

Back

Velocity is the rate at which an object changes its position. It is a vector quantity, meaning it has both magnitude and direction.

Front

How do speed and velocity differ?

Back

Speed is a scalar quantity with only magnitude, while velocity is a vector quantity with both magnitude and direction.

Front

What is the SI unit of speed?

Back

The SI unit of speed is meters per second (m/s).

Front

Can an object have constant speed but changing velocity?

Back

Yes, if an object moves in a circular path at constant speed, its velocity changes due to the change in direction.

Front

How is average speed calculated?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the formula for velocity?

Back

Velocity = Displacement / Time

Front

Can velocity be negative?

Back

Yes, velocity can be negative if the object is moving in the opposite direction to the chosen reference direction.

Front

What is uniform velocity?

Back

Uniform velocity means an object moves in a straight line with constant speed and direction.
