1. What is motion?
An object is in motion when it’s distance from another object changes.
What is a reference point?
It is an object or place used to determine whether an object is in motion.
Calculating Speed…
Speed is calculated using the following equation:
s = distance / time
units Miles per Hour…. Meters per Second

2. What is the speed of the object below at 40 seconds?
Speed = distance / time
= 50 m / 40 s
= 1.25 m/s

3. What the difference between speed and velocity?
Speed is the rate of distance / time
Velocity is speed AND DIRECTION of an object
What is happening to the speed of the object below?
Speed is : increasing at 5 seconds
and 25 seconds…
The object stops moving at 65 seconds
