An object that is being moved over a surface will experience a force in the opposite direction as its movement.     

The magnitude of the force depends on the coefficient of kinetic friction between the two kinds of material.

A frictional force occurs when you try to push an object alongside a surface.

Sinceaverage speed is the rate position changes, average speed = distance traveled/time taken.]]> 2017-08-28 22:04:25 UTC https://padlet.com/309681/sgjlcm04q9mm/wish/183256021 Net Force 309681 https://padlet.com/309681/sgjlcm04q9mm/wish/183256375 In physics, the Net force is the overall force acting on an object.

To calculate net force, the body is isolated and interactions with the environment or other constraints are represented as forces and torques in a free-body diagram.

Anytime there is a balanced force on an abject, the object stays still or continues moving continues to move at the same speed and in the same direction.
