in the blocks, reaches a speed of \(10\, m\, s^{-1}\) in 4 seconds. Calculate the acceleration. We sometimes refer to a moving object as having a 'constant acceleration' or a 'uniform acceleration'.
This makes it easier to read the measurements. For example, the speed a cricket ball travels might be measured in metres per second (m/s), while a car's speed might be measured in miles per hour ...
