Acceleration = (v - u)/t
Replace each variable in the equation with their units
Acceleration = (m/s - m/s) / s
Same common denominator
(m - m/s)/s
Apply divison of fractions
(m-m)/s*s
(m/s^2)
Note: I know m - m = 0 but they are just units expressing metres!

the general form of the units for acceleration are distance per time squared, such as m/s2.
Speed . . . Any unit of length or distance/any unit of time Acceleration . . . Any unit of speed/any unit of time
Assuming that your units of velocity are in units/second Acceleration = (velocity 2 - velocity 1) / time Acceleration = (4.9 - 0) / 3 Acceleration =1.63 *With correct significant figures the answer is 2
Acceleration is not measured in meters/second. Meters/second is a unit of speed. Since acceleration is defined as change of speed divided by time, the units are meters/second/second, usually written as meters/second2.
Speed = (distance covered) divided by (time to cover the distance) Speed = (magnitude of acceleration) multiplied by (time the acceleration has acted)
