... 19. E. I. is, of course, true. II is also true, because the displacement (along the circumference) is always at right angles to the force (gravity), so Fx cos = 0. Another way to see that the work done by the net force in uniform circular motion must be zero is the following argument. Say that th ...

NEWTON`S THIRD LAW ANSWERS
... The acceleration is so tiny because of earth’s enormous mass, it is undetectable. There is nothing in outer space for rocket exhaust gasses to push against. How then can a rocket accelerate in outer space? (And yes, we do know that they can accelerate in outer space, this is not a trick question!) ...

Newton`s Second Law
... A 10 kg object is subject to a net force of 25 N. What is the acceleration of the object in m/s2? The second law says a = F/m. Therefore a = 25 N /10 kg = 2.5 m/s2 If the object starts at rest, then how long will it be before its velocity is 25 m/s? You know that v = v0 + at and v0= 0. Rearranging g ...
