Calculating Speed

Front

What is speed?

Back

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

Front

How do you calculate average speed?

Back

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

Front

What is the formula for speed?

Back

Speed = Distance / Time.

Front

What units are used to measure speed?

Back

Speed is commonly measured in meters per second (m/s) or kilometers per hour (km/h).

Front

If a runner completes a 200 meter race in 20 seconds, what is their average speed?

Back

10 m/s.

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 that an object covers equal distances in equal intervals of time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur when an object speeds up, slows down, or changes direction.

Front

If a car travels 150 kilometers in 3 hours, what is its average speed?

Back

50 km/h.

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).
