Calculating Speed

Front

What is speed?

Back

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

Front

How do you calculate average speed?

Back

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

If a runner completes a 100 meter dash in 10 seconds, what is her average speed?

Back

10 m/s.

Front

What is the speed of an object that travels 60 meters in 4 seconds?

Back

15 m/s.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is instantaneous speed?

Back

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

Front

What is constant speed?

Back

Constant speed means an object travels the same distance in equal intervals of 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

What is acceleration?

Back

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

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

Back

60 km/h.
