... all of its lost KE was translational KE. While for the hoop, only half of its lost KE was lost translational KE (the other half was lost rotational KE). Both start out with the same KEtrans, but the hoop loses less KEtrans in going up the hill, so it finishes with more KEtrans than the puck. Greater ...

... 6. State Newton’s Second Law in words and then in the form of an equation. Ans. The acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. F = m x a. 7. How much force does a 20, 000 kilogram rocket develop to accelerate 1 m/s2? Ans. F = ...

... • By applying a force we can cause a rotating object to accelerate and change its rotational velocity. Rotational acceleration is the rate of change in rotational velocity. Δω α= t units: rev / sec2 or rad / sec2 Δv • Note: ‘α’ is analogous to linear acceleration (a = t ). Example: Spinning up a wh ...
