Momentum

This week we began to learn about momentum. We told that momentum is the movement of inertia, which makes it a vector quantity. This meaning that is has direction and magnitude. We also talked about the Law of Conservation of Momentum, which states that in an isolate system, momentum is conserved. Another element that deals with momentum directly is impulse. Impulse is defined as the change in momentum. Momentum is measured through mass and velocity. The momentum of an object can be found only when you multiply the objects mass by its velocity. My example is my turtle. We are going to say that my turtle is roughly 2 kg, which is kinda heavy for a turtle… I think. Anyway, we are also going to say that its velocity is about 5 m/s, which also may be a little too fast for the turtle. To find the momentum of the turtle we multiply the mass by the velocity. 2 kg x 5 m/s = 10 kg m/s.
