Physics 3-Motion 2.0 / 5 based on 1 rating ? PhysicsForces and MotionGCSEWJEC Created by: purplehydroplumCreated on: 23-05-16 14:39 How would you find a non constant acceleration? Change in speed over time 1 of 14 what is acceleration measured in? M/S2 2 of 14 What is velocity measured in? m/s 3 of 14 What must be included in any measurement for a constant acceleration equation (excluding time) A direction 4 of 14 Why? They are vectors 5 of 14 What is left/right represented by? A -/+ value 6 of 14 What objects do the constant acceleration equations work well for? Objects under the influence of gravity, objects on planets (acceleration form gravity is constant) 7 of 14 What is an important deature to consider when using these equations? Negligible air resistance/friction 8 of 14 Why, when calculating the acceleration of a falling object, is the final velocity not considered 0? It is the velocity just before it makes contact with the ground. 9 of 14 What can be said about the momentum of two interacting bodies, if there are no external forces acting? It is constant 10 of 14 What happens to energy that is 'lost' in a collision? IT's converted into heat or sound and transferred to the surroundings. 11 of 14 How can the Kinetic energy loss be found? KE before- KE after 12 of 14 What is the term for a collision where no kinetic energy is lost? An elastic collision 13 of 14 What is an inelastic collision? Where kinetic energy is lost during a collision 14 of 14
