If A and B are both the same height,

Do they have the same amount of Potential Energy?

Page 2: Work – Power Questions – 1

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?)

A B

Page 4: Work – Power Questions – 1

Work – Power Questions – 4

So which will have a faster acceleration here?

Page 5: Work – Power Questions – 1

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

???

Page 6: Work – Power Questions – 1

Work – Power Questions – 6

So considering acceleration (Question 4),

which will have a faster TIME here?

Which did we say gets to the bottom quicker?

Using the definition of acceleration, what is the time of each fall?
