Experiment 2...

Experiment 2
Does objects at rest remain at rest?

Objective:The main reason of this lab was to figure out if an object from rest would be the same or would it be diffrent from the force that is required to move an object constantly.

Hypothesis:I predicted that the force you put into moving the object from rest to greater is required more force then to keep the cart from moving.

Materials:
1-A spring
2-A cart
3-A Lumber Wood
4-A 8in string
5-A ruler
6-A 200(g)grams weight

Procedure:First we had ro tie the 8in string onto the front of the cart and then we had to tie a loop at the end of the string.

Then we had to put the 200 gram weight into the cart.We then had to make sure the srping scale was at 0, and we then attched the hook which was on the srping scale and attched it to the loop that was on the string.

We had to tug on the spring scale to keep the cart moving.I had to pull the cart across the table repeatedly to keep the cart going.

Data:Tug1-30(g)
Tug2-45(g)
Tug3-85(g)

Jerk1-20(g)
Jerk2-70(g)
Jerk3-40(g)

Constant Speed-30(g)
Faster Speed-45(g)

Conclusion:My hypothesis was true. It was true because their was more force required to moving the object from rest to greater. I learned that their are diffrent a diffrent type of force to you have to use.It all depends on the object.
