... should be. We should also check the scale of the answers. The angular velocity of the particle on the right is 0.628 rad/s, meaning that the particle travels through an angle of 0.628 rad each second. Because 1 rad ≈ 60°, 0.628 rad is roughly 35°. In Figure 7.2b, the particle on the right appears to ...

... In the track and field event known as the hammer throw, an athlete spins a heavy mass in a circle at the end of a chain. Once the mass gets moving at a good clip, the athlete lets go of the chain. The mass flies off in a parabolic arc; the winner is the one who gets the maximum distance. For male at ...

... This paper was meant to give a layperson’s an easy, straight forward explanation of scalar waves and scalar fields. After reading over 1500 pages on the subject, I became more confused than when I started, mainly because the more I read the more diverse and even contradicting explanations I got. Slo ...

... the wave.8 A straightforward calculation (see Wald (1984, pp. 65-6)) shows that Eq. (5) implies that ka ≡ ∇a S, the normal vector to surfaces of constant phase, is null; thus k a is also tangent to the surfaces of constant phase.9 Moreover, k a can be shown to be geodesic, i.e., k n ∇n k a = 0. This ...
