Newton`s Laws: Explaining Motion
... Notice that, in paraphrasing Newton’s first law, we have used the term velocity rather than the term speed. Constant velocity implies that neither the direction nor the magnitude of the velocity changes. When the object is at rest, its velocity is zero, and that value remains constant in the absence ...

... We will need to take precautions if we want all the states to be of same temperature. We will discuss this in the future. If the particles are not spherical, things get more complicated. There are numerical methods tailored to this type of application for maximum numerical efficiency. If the number ...

... A falling person is gaining momentum all the way down as gravity pulls on them. When they reach the ground and stop, whatever they hit has to impart just the right amount of impulse to take away all their momentum. If they had 1000 kg·m/s of momentum, they would need to receive –1000 N·s of impulse ...

... Of these three equations, the top equation is the most commonly used. The other two equations are seldom (if ever) used. An application of projectile concepts to each of these equations would also lead one to conclude that any term with ax in it would cancel out of the equation since ax = 0 m/s/s. ...
