How is acceleration measured?
It is the rate of change of velocity per unit time. Acceleration is expressed in terms of distance per second per second, or distance per second squared. Typically in feet per second squared or meters per second squared. Velocity, or speed in simpler layman’s terms, is a reference to a constant motion. Like 55 MPH. For each hour you spend at a speed of 55 MPH, you will travel 55 miles. As long as your speed is constant, the distance per unit time is constant. If you CHANGE your speed (speed up or slow down), this process is known as acceleration because the speed is no longer constant over time. When you arrive at a new, constant speed, then acceleration is zero again and distance traveled per unit time is again constant. Now that I’ve thoroughly confused you…
