Things in Motion: Speed and Velocity

The video tutorial explains how to measure speed, which is the distance covered per unit of time. It discusses speed limits in miles per hour and kilometers per hour, and provides an example of calculating speed. The concept of velocity is introduced, which includes both speed and direction.

What is speed a measure of?

• The weight of an object

• The amount of time taken to cover a distance

• The amount of distance covered per unit of time

• The direction of travel

If a vehicle is traveling at 35 miles per hour, what does this mean?

• It covers 35 kilometers in one minute

• It covers 35 kilometers in one hour

• It covers 35 miles in one hour

• It covers 35 miles in one minute

How do you calculate the speed of a car that travels 80 kilometers in two hours?

• Add 80 kilometers to two hours

• Subtract two hours from 80 kilometers

• Divide 80 kilometers by two hours

• Multiply 80 kilometers by two hours

What additional information does velocity provide compared to speed?

• The time of travel

• The direction of travel

• The color of the object

• The weight of the object

If a stream has a velocity of 20 kilometers per hour North, what does this indicate?

• The stream flows 20 kilometers in one hour

• The stream flows 20 kilometers per hour in an eastern direction

• The stream flows 20 kilometers per hour in a southern direction

• The stream flows 20 kilometers per hour in a northern direction
