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.

Experiment 1....

Do objects at rest really remain at rest unless acted upon by external foreces?

Objective:The whole reason for this lab report was to learn the Newtons laws of motion and to learn more of force. We had to do an experiment and we had to complete a lab to understand.


Hypothesis:I predict that the cart will move and it will roll over and fall when the ramp is pulled out from under it, and that it would be the same force required.

Procedure:First, We had to to put the ramp flat on the table,with it being 12" over the egde of the table.We had to measusre it to make sure that it was exactly at 12".

Second,we took the cart and placed it on top on the ramp which was on the table.

Third,Then we had to stand to one side and quickly pull(jerk)the ramp from under the cart.

Fourth,we had to do the same thing 4-5 times.

Data:
Trial 1-The cart didnot roll or move it just stayed the same.
Trial 2-Same as Trial 1.
Trial 3-Same as Trial 2.
Trial 4-Same as Trial 3.

Conclusion:My hypothesis was correct. The newton law stated that "An object at rest remains at rest" was true.Througout the whole lab the cart stayed at at rest.
