In computing for acceleration, the change in velocity is divided by the time. Since the unit for velocity is expressed in meter per second (m/s), and the unit for time is seconds (s), therefore, the SI unit for acceleration is written as meter per second squared or m/s 2 ^{2} 2.
(a) What is the acceleration, in meters per second squared, of the particle at time t 0 = 1.0 s? (b) What is the displacement, in meters, of the particle between times t 0 = 1.0 s and t 1 = 3.0 s? (c) What is the distance traveled, in meters, by the particle between times t 0 = 1.0 s and t 1 = 3.0 s?
Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are \(\mathrm{m} / \mathrm{s}^{2}\), meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. Recall that velocity is a vector—it has both magnitude and direction.
If we multiply both sides of the definition of acceleration, a = Δ v Δ t , by the change in time, Δ t , we get Δ v = a Δ t . Plugging in the acceleration 4 m s 2 and the time interval 9 s we can find the change in velocity: Δ v = a Δ t = ( 4 m s 2) ( 9 s) = 36 m s. Multiplying the acceleration by the time interval is equivalent to ...
