Question

Barry used a ramp to transport a load to a loading truck. The ramp made work easier by
Answer choices:
1.increasing the size of the input force.
2. reducing the input force to zero.
3. changing the distance over which the input force was exerted.
4. reducing the output force to zero.

Answer 1

@travisbrown372 @amistre64 @abb0t

Answer 2

Work = Force x distance

since the Work is the same regardless or which distance we travel.

if distance increases, force has to decrease to balance out the same

Answer 3

at least that how im remembering this :)

Answer 4

...?

Answer 5

@travisbrown372 help?

Answer 6

im here now

Answer 7

I know right...btw don't go to the math chat, the noobs are crowding there and saying bad stuff

Answer 8

ok

Answer 9

how is it confusing to you?

Answer 10

I just don't get how one of the answers could answer the question. It doesn't make sense to me because I don't get the answers

Answer 11

2 or 4 i think

Answer 12

i dont get the question ... is what im confused about if anything is the phrase "made work easier"

Answer 13

the force needed to do the same amount of work is reduced by a ramp; but not to zero

Answer 14

i spose as the ramps distance increases towards infinity; the force needed to accomplish the same amount of work goes to zero; or at least the up force

Answer 15

So....the answer would be? I still don't get it

Answer 16

maybe the input force is the force in the direction of motion?
