SP1-Motions 4.0 / 5 based on 1 rating ? PhysicsForces and MotionGCSEEdexcel Created by: keyaan MartinCreated on: 18-03-17 11:12 What are vector quantities and examples? Vector quantities are quantities that have both size and direction. Some examples are displacement- velocity- acceleration- force- weight- momentum 1 of 7 What are scalar quantities and examples? Scalar quantities do not have direction and have only size. Some examples are distance- speed- time- power- energy 2 of 7 What is the equation for average speed? Speed = distance ÷ time 3 of 7 How do you calculate acceleration? Acceleration = change in speed ÷ time taken 4 of 7 What is acceleration free fall? free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s, 5 of 7 How do you calculate acceleration from a velocity/time graph? the gradient of the line 6 of 7 How do you calculate the distance on a velocity/time graph The area under the line in a velocity-time graph represents the distance travelled. 7 of 7
