What is Acceleration
-
Decreasing Speed
Objects can also slow down, this change in speed is called deceleration.
Changing Direction
Even an object traveling at a constant speed can be accelerating. Acceleration can be a change in direction as well as a change in speed.
In everyday language, acceleration means the process of speeding up.
Scientists define acceleration as the rate at which velocity changes. In science, acceleration refers to increasing speed, decreasing speed, or changing direction.
Calculating Acceleration
-
To determine the acceleration of an object moving in a straight line, you must calculate the change in speed per unit of time.
An airplane accelerates at the rate of 8 m/s2. This means that the airplanes speed increases by 8 m/s every second.
Graphing Acceleration
Speed Versus Time Graph
In a graph if the line slants upward, your speed was accelerating. If it's straight you went a constant speed.
