What is the scientific equation to calculate the acceleration of an object?
a = (change in velocity) ÷ time
a = (change in DISTANCE) ÷ time
a = (change in DISTANCE) * (change in velocity)
a = (change in DISTANCE) * time

A runner is moving at 1.4 m/s, but speeds up to 2.2 m/s in four seconds. How could you determine how much the runner accelerated?
a = (2.2m/s - 1.4m/s) ÷ 4 seconds
a = 2.2m/s ÷ 4 seconds
a = 1.4m/s * 2.2m/s
a = (1.4m/s + 2.2m/s) * 4 seconds

You can calculate the weight of a 10kg object on Earth by...
W = 10kg * 9.8m/s/s
W = 10kg ÷ 9.8m/s/s
W = 2 * 10kg
Mass and weight are the same thing, so the object's weight is 10kg.

The graph shows the distance traveled by a tortoise and a hare during a race.
How could somebody determine the velocity of the tortoise during the first five minutes of the race?
v = (10m - 0m) ÷ 5min
v = 50m ÷ 25min
v = 10m * 5min
v = 10m + 30m
