Physics Forces Cards for forces 1.0 / 5 based on 1 rating ? PhysicsGCSEAQA Created by: Elliot LinseyCreated on: 07-10-12 20:18 Difference between Speed and Velocity? Speed = how fast you're going. Velocity = how fast you're going + in what direction 1 of 12 Speed and Velocity Formula? Speed = Distance/Time 2 of 12 Gradient of a graph formula? Gradient of a Graph = Change in Y/Change in X 3 of 12 Acceleration Formula? Acceleration (m/s(Squared)) = Change in Velocity/Time taken 4 of 12 Gravitational Potential Energy Formula? GPE (J) = Mass x Gravity (Always 10 on Earth) x Height 5 of 12 Weight Formula? Weight = Mass x Gravitational Field Strength 6 of 12 Resultant Force Acceleration Formula? F (Resultant force) = M (Mass in Kg) / A (Acceleration in m/s(Squared)) 7 of 12 Work Done Formula? Work Done (J) = Force x Distance 8 of 12 Kinetic Energy Formula? Ek = 0.5 x Mass x Speed(Squared) 9 of 12 Falling Objects Convert? GPE into Ek 10 of 12 Power Formula? Power (J/s) = Work Done/Time Taken 11 of 12 Momentum Formula? Momentum (kgm/s) = Mass (Kg) x Velocity (m/s) 12 of 12
