Speed and Velocity

Front

What is the definition of speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is the definition of velocity?

Back

Velocity is speed in a given direction.

Front

What is the formula to calculate speed?

Back

S = d/t (Speed = Distance / Time)

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

If a car travels 60 miles in 1 hour, what is its speed?

Back

60 miles per hour (mi/hr).

Front

If a runner completes a 400m lap in 50 seconds, what is their speed?

Back

Speed = 400m / 50s = 8 m/s.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

An object moves with a constant speed of 20 m/s for 10 seconds. How far does it travel?

Back

Distance = Speed x Time = 20 m/s x 10 s = 200 m.
