... The sums of the forces in the y and r directions are then ΣFy = FN cos θ − Ff r sin θ − W = 0 ΣFr = FN sin θ + Ff r cos θ = mac We would like to solve for the frictional force to get the answer. Comparing the two equations above we can see that both equations have FN as the first term, but one is mu ...

... A force is anything that can cause a change to objects. Forces can change the shape of an object, accelerate or slow an object, and change the direction of a moving object. Types of Forces 1. Gravitational force is an attractive force between objects with mass. It is greater if the mass of the objec ...

... In activity 3.2 we found that the force of gravity causes the velocity of a cart to increase as it rolls down a ramp. We now calculate the rate of change in velocity (the acceleration) of the cart as it rolls down the ramp. 1) Use two blocks to support the wooden ramp. Hold the cart at rest at the t ...
