... Mass: Mass is the amount of material present in an object. This dimension describes how much material makes up an object. Often, mass and weight are confused as being the same because the units used to describe them are similar. Weight is a derived unit, not a fundamental unit, and is a measurement ...

... We write ∑F = ma from the force diagram for the elevator: y-component: FTmax – mg = ma, or FTmax = m(a + g) = (1200 kg)(0.0600 + 1)(9.80 m/s2) = 5.04104 N. The minimum tension will be exerted by the motor when the elevator is accelerating downward. We write ∑F = ma from the force diagram for the ...

... (d)2, (ds)2 is equal to zero. In this case, (dx) = d = (cdt). Hence, dx = cdt, or dx/dt = c. But dx/dt is a velocity. For it to equal c, it must be the world line of something moving at the speed of light. Thus (ds)2 = 0 represents a light ray and the world line is called lightlike. Lightlike worl ...

This means that if you have several objects in a system, perhaps interacting with each other, but not being influenced by forces from outside of the system, then the total momentum of the system does not change over time. However, the separate momenta of ...
