in your own words, what you say about  speed, force, and friction and how they are used together?

May 11th, 2015

speed= how fast you are moving

force = power that moves or accelerates /decelerates

friction =slowing down of motion when two surfaces are in contact with each other

Usually a force is applied to an object in contact with a surface (ground/air/water)  increasing the speed. As the object stops, friction becomes important  to counteract the dying force.
