Does the earth attract the moon with a force that is greater or smaller or the same as the force with which the moon attracts the earth? Why? According to the universal law of gravitation, two objects attract each other w ...

... 7) Why is less force needed to keep an object moving than to start it moving? Less force is needed because the inertia of the object wants to keep it moving. To start an object moving you have to overcome its wanting to stay still (its inertia) 8) Define inertia and state Newton’s 1st law. Inertia i ...

Newton`s laws, part 1(Sep 20)
... Forces are important since they are the starting point of Newtonian mechanics. The idea is to analyze each body in a problem in isolation to determine the forces that act on it. If we know the initial position and velocity of the body, we then solve Newton’s equations of motion, to find out where th ...
