#### Waves A3 Revision Sheets + Answers (AQA GCSE Physics )

(0)
Designed for the Physics AQA GCSE these A3 revision sheets cover all of the content that students are required to know for the topic ‘Waves’. This resource is designed so that students can work independently to gather the content needed for this topic. There are four sheets in total. The first two are for students sitting Combined Science (Trilogy) GCSE and the last two are additional sheets for Triple Physics students Formatted to be printed on A3 but can easily be printed on A4.

#### Force and Acceleration - Newton's Second Law

Explain why two identical cars that have different loads will have different accelerations. Explain why heavier vehicles have greater stopping distances than light vehicles, assuming the same braking force. Students will practice recalling and rearrange the formula F=ma with units, solving problems with the formula F=ma and prior knowledge of forces and applying Newton’s Second Law to the Top Gear video.
