Forces and Motion

Forces and Motion

1. Velocity and acceleration

   • Speed
     • Speed Distance and time formula
   • Velocity
     • Speed + Direction
     • Acceleration
       • How quick the velocity is changing
       • Formula : Acceleration = Change in Velocity/Time taken
   • m/s

2. Gravity

   • Force of attraction between all masses
   • On earth makes things accelerate towards the ground at 10m/s2

3. Mass

   • Amount of stuff in an object
   • Kg

4. Weight

   • Caused by the pull of gravity
   • Force measured in Newtons
   • Weight = mass x gravitational field strength

5. Friction
