Circular Motion
... • Kepler was familiar with Galileo’s concepts of inertia and accelerated motion, but he failed to apply them to his own work. • Like Aristotle, he thought that the force on a moving body would be in the same direction as the body’s motion. • Kepler never appreciated the concept of inertia. Galileo, ...

momentum
... Momentum in a Closed, Isolated System Under what conditions is the momentum of the system of two balls conserved? The first and most obvious condition is that no balls are lost and no balls are gained. Such a system, which does not gain or lose mass, is said to be a closed system. The second co ...

Force and Motion
... • is the magnitude of the pulling force exerted by a string, cable, chain, or similar object on another object. • It is the opposite of compression. It is a “response force” • That is to say, if one pulls on the rope, the rope fights back by resisting being stretched • Ropes, strings, and cables can ...
