Physics Paper 1 Forces and Motion 0.0 / 5 ? PhysicsForces and MotionGCSEEdexcel Created by: Alfie GardCreated on: 03-02-20 17:52 What is a Scalar? Something that only has Magnitude (Size) not direction. 1 of 11 What is a Vector? A vector is a quantity that has both a magnitude and a direction. 2 of 11 How do you work out Speed? Speed (m/s) = Distance (m) / Time (s) 3 of 11 How do you work out Velocity? Velocity (m/s) = Distance (m) / Time (s) 4 of 11 How do you work out acceleration? Acceleration (m/s squared) = Change in velocity (m/s) / Time (s) 5 of 11 How do you work out work done? Work done (Joules) = Force (N) / Distance (m) 6 of 11 How do you work out the equation for power? Power (Watts) = Work done (Joules) / Time taken (s) 7 of 11 What is a contact force? Contact forces are forces which are physically touching each other. 8 of 11 What is a non-contact force? A non-contact force are forces which are physically seperated. 9 of 11 What is a resultant force? The resultant force is a single force that has the same effect as all of the original forces acting together. 10 of 11 How to calculate resultant force? You must subtract the smaller force from the large force. 11 of 11
