P6.1 Physics on the move
Summary Learners will use their knowledge of forces and motion to develop their ideas about how objects are affected by external factors. They will develop a better understanding of these external factors to be able to understand how the design of objects such as cars may be modified to operate more safely. Underlying knowledge and understanding Learners should be familiar with how forces affect motion of objects. They may already have some knowledge of how vehicles are adapted to increase safety.
Common misconceptions Learners tend to confuse the factors that affect thinking distance and braking distance, thinking that alcohol, drugs and tiredness will affect braking distance rather than thinking distance. It needs to be made clear the distinction between these two terms and that the combination of these gives us the stopping distance.
