Friction

This experiment is made for describing friction. The idea is that if you put a solid object on a ramp and start to tilt the ramp upward, there is a point where the object will start to slide. That is the angle where the force of gravity is strong enough to overcome the static friction and that will check the friction between object and the ramp.Friction can be calculated when we compare the force of the weight and the resistance that is caused from the friction.
