Velocity and Speed Review_Phy6PreComp

Front

What is speed?

Back

Speed is the distance traveled per unit of time, measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, measured in meters per second (m/s) with a direction (e.g., 40 m/s north).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken: Average Speed = Total Distance / Total Time.

Front

What is the difference between speed and velocity?

Back

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

Front

If an object travels 100 m North and then 50 m South, what is the total distance traveled?

Back

The total distance traveled is 100 m + 50 m = 150 m.

Front

If an object travels 100 m North and then 50 m South, what is the displacement?

Back

The displacement is 100 m - 50 m = 50 m North.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time.

Front

What is the unit of speed?

Back

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

Front

What does it mean if an object has a velocity of 0 m/s?

Back

A velocity of 0 m/s means the object is at rest and not changing its position.

Front

How do you convert speed from km/h to m/s?

Back

To convert km/h to m/s, divide the speed by 3.6.
