Speed and Velocity

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, such as 60 mph north.

Front

What is the formula for calculating speed?

Back

speed = distance / time

Front

What is average speed?

Back

Average speed is the total distance traveled divided 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 unit is commonly used to measure speed?

Back

m/s (meters per second) or mph (miles per hour).

Front

If a car travels 120 miles in 2 hours, what is its average speed?

Back

Average speed = 120 miles / 2 hours = 60 mph.

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 is acceleration?

Back

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

Front

If a plane travels 3000 miles west in 5 hours, what is its velocity?

Back

Velocity = 3000 miles / 5 hours = 600 mph west.
