Vectors and Velocity 0.0 / 5 ? PhysicsForces and MotionGCSEEdexcel Created by: kat-yCreated on: 10-12-16 21:34 Define VECTOR A quantity that has a magnitude (size) and direction. 1 of 8 Give four examples of a vector quantity. Force, acceleration, momentum, velocity 2 of 8 How is a SCALAR quantity different from a VECTOR quantity? A scalar quantity only has a magnitude. 3 of 8 Give an example of scalar quantity. Speed/Temperature/Energy 4 of 8 Displacement is... the distance travelled in a particular direction - it is a quantity that has a direction 5 of 8 Velocity is... the speed of an object in a particular direction (usually measured in metres per second) 6 of 8 Force is... an interaction on an object that can cause it to accelerate 7 of 8 Acceleration is... a measure of how quickly the velocity of something is changing. Positive when speeding up, negative when slowing down. 8 of 8
