Describing Motion Hard Problems

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

If Mufasa lives 100 meters from his friend's house and takes 50 seconds to get there, what is his average speed?

Back

2 m/s.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the starting point to the endpoint.

Front

What is total distance run if a runner goes 50 m west and then 30 m east?

Back

Total distance run is 80 m.

Front

If a student walks 10 m east and then 8 m west, what is the total distance walked?

Back

Total distance walked is 18 m.

Front

What is a rate in motion?

Back

A rate in motion is a measure of how fast something is moving, typically expressed as distance per unit of time, such as kilometers per hour or meters per second.

Front

Which example represents a rate?

Back

A person running 2 km in 10 minutes.

Front

How do you find the time taken if you know distance and speed?

Back

Time = Distance / Speed.

Front

If an old lady rolls down a hill at 3 m/s and the hill is 36 m long, how long does it take her to reach the bottom?

Back

It takes her 12 seconds.
