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

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

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
