Acceleration. Acceleration is defined as the rate of change of velocity. In other words, it describes how much an object's velocity changes every second. The equation below is used to calculate the average acceleration of an object: Where: = acceleration in metres per second squared (m/s 2) = change in velocity in metres per second (m/s)
Edexcel GCSE Physics Motion and Forces Calculating Acceleration Acceleration is the rate at which an object’s velocity changes over time, measured in metres per second squared (m/s 2 ) For example, when a driver presses down on the accelerator, the car speeds up, and its velocity increases each second.
Example: Acceleration from A to B. Change in velocity 20 m/s in 5 seconds, so the acceleration is 20 ÷ 5 = 4 m/s/s. If the line on a velocity-time graph is curved it indicates a changing rate of acceleration. In this example, the acceleration is greatest at the start of the motion and gradually decreases from about 5 seconds.

Calculating Uniform Acceleration. The following equation of motion applies to objects moving with uniform (constant) acceleration: (final speed) 2 − (initial speed) 2 = 2 × acceleration × distance travelled Where: x = distance travelled in metres (m). u = initial speed in metres per second (m/s). v = final speed in metres per second (m/s). a = acceleration in metres per second squared (m/s 2)
Where: acceleration, a, in metres per second squared, m/s²; change in velocity, ∆v, in metres per second, m/s; time, t, in seconds, s; Question: A high-speed train accelerates at a constant rate in a straight line. The velocity of the train increases from 30 m/s to 42 m/s in 60 seconds. 1. Calculate the acceleration of the train.
