Question

If we decrease the amount of force, and keep all other factors the same, what will happen to the amount of work? (2 points)

The amount of work will go down because the distance will decrease.

The amount of work will go up because the distance will decrease.

The amount of work will go down because the distance will increase.

The amount of work will go up because the distance will increase.

Answer 3

If force is decreased then the amount of work is decreased.

Answer 4

k thx

Answer 5

What would we need to know to calculate both work and power? (2 points)

energy, force, and time

force, distance, and time

force, mass, and distance

mass, force, and energy

Answer 6

The best one in my opinion is B. Force,distance, and time

Answer 7

sweet

Answer 8

If you are given force and distance, you can determine power if you know (2 points)

joules.

energy.

time.

watts.

Answer 9

?

Answer 10

I'm not 100% sure on this one but I know that Work = Force x Distance I'm pretty sure its not Joules. Time just doesn't seem logical since we don't have a rate/time of how long it takes. and im pretty sure energy you get with velocity and mass so I am pretty sure that just leaves Watts in my opinion, joules is possible I could be wrong though.

Answer 11

In order for work to take place (2 points)

the energy present must be related to the movement of the object.

the force applied must be a balanced force resulting in motion of the object.

the force applied must cause the movement of the object in the same direction as the force.

the movement of the object must be the cause of the force.

Answer 12

I believe that it is The force applied must cause the movement of the object in the same direction as the force.

Answer 13

A woman steps in front of a child to keep him from running off. Which term best describes this example? (2 points)

negative work

positive work

negative force

positive force

Answer 14

If a person is pushing at a door that wont open blocking him going forward what do you think? I can tell you its not positive.

Answer 15

Which statement describes how work and power are similar? (2 points)

You must know force and distance to calculate both.

You must know energy and force to calculate both.

You must know velocity and time to calculate both.

You must know time and energy to calculate both.

Answer 16

work = force x distance or W = F x d
P = W / t

Work = Force * distance
Power = Work / time

Answer 17

In my opinion the best answer is going to be you need force and distance for them both.

Answer 18

Since another equation for power is

Power = work/time = Force * displacement/time
Power = Force * displacement/time
Power = force * velocity

Answer 19

thanks one more ind ur freeThe same force is applied to two skateboards. One rolls across the room and the other moves a few feet and comes to a stop. Where was there more work done? (2 points)

The skateboard that traveled the shorter distance shows more work because there was more resistance.

The skateboard that traveled the longer distance shows more work because it was lighter.

The skateboard that traveled further shows more work because the distance was greater.

The skateboard that traveled the shorter distance shows more work because the force was greater

Answer 20

I believe it is (C) The skateboard that traveled further shows more work because the distance was greater.
