... true"!). In relativity we must change Newton's II law F = ma since m is not constant. We can use the momentum instead : F = ma = m(v-u) = mv - mu and then impulse = Ft = change in momentum = p = mv - mu which for an infinitely short time dt becomes: Fdt = dp and dividing with dt then: F = dp/dt (f ...

Period 3 Activity Sheet: Motion and Forces
... 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 ...

The essential point being made is that a moving object slows down because something has interfered with it. Slowing down is not a property built into the object. We should search for the cause outsi ...

Newton`s Second Law
... In this experiment a low friction air track will be used to test the validity of Newton’s Second Law. A hanging mass will be attached to a glider placed on the air track by means of a light (negligible mass) string. By varying the amount of mass that is hanging we will vary the net force acting on t ...
