![]() Students seldom identify a car turning a corner at constant speed as accelerating because their common understanding requires the object to be changing speed for it to be accelerating.Įven senior students regularly confuse ‘acceleration’ and ‘speed’ for example they may think that if speed is increasing then acceleration is also increasing. However, it is much more difficult to determine if an object already moving is changing its speed unless the change is dramatic. ![]() Students are familiar with objects accelerating from rest or braking, for example a car speeding up or to a lesser extent slowing down at the traffic lights. Accelerated motion is also a difficult concept for students because it occurs when an object changes It is very difficult to tell with the naked eye if an object is accelerating (for example, a ball flying through the air) and so students do not tend to think of motion in terms of whether it is accelerated or not.
