Example of air friction
WebThe coefficient of restitution (COR, also denoted by e), is the ratio of the final to initial relative speed between two objects after they collide.It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision.A perfectly inelastic collision has a coefficient of 0, but a 0 value does not have to be perfectly inelastic. It is measured in the Leeb rebound … WebFree Fall Motion. As learned in an earlier unit, free fall is a special type of motion in which the only force acting upon an object is gravity. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects ...
