Understanding Speed and Motion Concepts

What are the two basic factors needed to describe motion and speed?

• Color and size

• Temperature and pressure

• Weight and height

• Distance and time

In the first example, which car is faster?

• The yellow car

• Neither car is fast

• Both cars are equally fast

• The blue car

Why is the yellow car faster in the first example?

• It covers the distance in less time

• It is a newer model

• It is lighter

• It has a bigger engine

In the second example, which car covers a longer distance?

• Both cars cover the same distance

• Neither car covers any distance

• The yellow car

• The blue car

What conclusion can we draw from the examples about speed?

• Speed depends on the color of the car

• Speed is determined by distance and time

• Speed is not related to distance or time

• Speed is only about how fast a car looks
