motion and speed

What is a reference point?

• The speed of an object in a particular direction

• How far an object travels in a specific amount of time

• A non-moving object in the background that we compare another object to

• The rate at which the speed of an object changes

What two pieces of information are needed to determine the speed of an object

• speed and direction

• distance and direction

• time and direction

• distance and time

Definition for speed

• How far an object travels in a specific amount of time and direction
