Work – Power Questions – 1 If A and B are both the same height, Do they have the same amount of Potential Energy?

Work – Power Questions – 2 If A and B are both the same height... At the bottom, do they have the same speed?

Work – Power Questions – 3 Which has a bigger acceleration? (Hint: which speeds up faster, as it falls?) AB

Work – Power Questions – 4 So which will have a faster acceleration here?

Work – Power Questions – 5 If for a similar block/incline system the acceleration is larger, and we know Delta V is the same for each block, What happens to the time? const ???

Work – Power Questions – 6 So considering acceleration (Question 4), which will have a faster TIME here?
