Answer the following concisely, in no more than three sentences. 1. In uniform circular motion we have an acceleration and the speed doesn't change. But in projectile motion the speed does change under constant acceleration, why are they both classified as uniform acceleration phenomena? 2. Explain, in terms of Newton's Laws, why a quick jerk on a string may cause it to break, whilethe same change in momentum performed over a longer time will not. 3. Explain, from a force standpoint, why you need to reduce your normal driving speed aroundcurves when it rains. 4. If an object is in equilibrium (no net forces acting on it) it has a constant velocity. Is morework required to keep it in motion? 5. Suppose you have a coin that is flat on one side, and the mass of the design on the other sideis fifty-five percent of the total mass. Is it possible to stand the coin on end?
