Newton’s laws of motion



Newton’s laws of motion were published towards the end of the 17th century, but are still used today to describe and predict the motion of objects under one or more forces, and continue to be used in fields as diverse as bridge design, biomechanics and space travel.

This video summarise Newton’s first, second and third laws and how they will be tested in your exam, before covered the required practical activity for this part of the course which focuses specifically on Newton’s second law.

Please note that this video includes some higher tier-only content.
