Speed and Velocity

Front

What is the difference between speed and velocity?

Back

Speed describes how fast something is going, whereas velocity describes how fast something is going and in which direction.

Front

What is a unit of speed?

Back

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

Front

If a person walks at 2 m/s for 12 seconds, how far do they travel?

Back

24 m (distance = speed × time = 2 m/s × 12 s).

Front

If a car travels at an average speed of 110 km/h, how long will it take to travel 715 km?

Back

6.5 hours (time = distance/speed = 715 km / 110 km/h).

Front

How long does it take to travel 50 km at a speed of 10 km/h?

Back

5 hours (time = distance/speed = 50 km / 10 km/h).

Front

Define speed.

Back

Speed is the distance traveled per unit of time.

Front

Define velocity.

Back

Velocity is the speed of an object in a specific direction.

Front

What is the formula for calculating distance?

Back

Distance = Speed × Time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating time?

Back

Time = Distance / Speed.
