| What are Newtons 3 laws? | 1. Balanced forces mean no change in velocity 2. A resultant force means change in acceleration. 3.If object A exerts a force on object B, object B exerts the exact opposite force on object A. |
| What is the equation which links force, mass and acceleration? | F=ma (force=mass x acceleration). |
| What are the equations for acceleration? | 1. Final velocity-initial velocity divided by time taken. 2. Force divided by mass. |
| What is the difference between speed and velocity? | Speed is a scalar quantity, while velocity is a vector quantity (scalar quantities only have a size, wheres vector quantities have a size and direction). |
| What differences are there between weight and mass? | 1. Weight depends on gravity, whereas mass is constant through out the universe. 2. Weight is measures in Newtons, mass is measures in Grams. |
| What are the 3 different types of friction? | 1. Friction between solid surfaces which are gripping. 2. Friction by solid surfaces which are gliding past each other. 3. Drag or air resistance. |
