Testing The Forces Affecting The Distance A Margarine Tub

Travels.

Introduction:

We are proving for actions or influence that accelerates, or changes the speed of, an object. An object experiences a force when it is pushed or pulled by another object. For illustration, jostling a stationary ball applies a force that causes the shopping ball to speed up. Besides a dropped ball accelerates towards the land because of the presence of the gravitative force ; electrical charges attract or repel each other because of the presence of an electric force.

Normally, several forces act on an object at one time. If multiple forces combine to give a net force that is zero, so the object will non derive velocity or lose velocity ; the object will either stay motionless or go on traveling at a changeless velocity.

Plan:

In this experiment I will be proving to see if different forces being added to a oleo bath, affects the distanced the bath is propelled.

Possible variables to prove ;

1 ) Adding weight to the oleo bath.

2 ) Changing the tenseness of the elastic set.

3 ) Changing the distance the set is pulled back.

4 ) Adding elastic sets.

5 ) Change the surface ( e.g. concrete )

Basic setup:

? Margarine bath

? Elastic sets

? Metre regulation

? Weights ( 100g-1kg )

? 2x bases

Method V1:

In this trial I tested to see if adding more elastic set affects the distance that the marg bath travelled. I set the setup up shown in the diagram above. I pulled the set s back 10 centimeter every clip. I besides added a fixed weight in the bath of 500g ; this helped to give more accurate consequences. First I put one set on between the bases and pulled the marg tub back 10cm and released it, and took down the distance it travelled. Then I added another elastic set and did the same thing. I added 10 elastic sets in entire, and repeated the whole trial over three times.

Prediction V1:

If you add more elastic sets to the base and draw the marg tub back 10cm every clip, the bath will go farther. Because there will be a much larger force being added to the marg bath, this will do the bath to speed up and therefore going a farther distance. If you have one set and you add another, the force will be doubled etc.

Consequences:

Number of sets added 1 ) distanced travelled ( centimeter ) 2 ) distanced travelled ( centimeter ) 3 ) distanced travelled ( centimeter ) Average distance ( centimeter )

8 80 79 88 82

V1 Conclusion

My consequences and chart show that my anticipations are right. I predicted that if you add more elastic sets to the base and draw the marg tub back 10cm every clip, the bath will go farther. Because there will be a much larger force being added to the marg bath, this will do the bath to speed up and therefore going a farther distance. If you have one set and you add another, the force will be doubled etc My graph has a consecutive tendency line, this tells me, when the force is increased ( adding an elastic set ) the distanced travelled by the bath additions. So every clip an elastic set is added the force on the marg bath additions to a point where it starts to diminish somewhat.

Method V2:

In this trial I tested to see if adding more weight affects the distance that the marg bath travelled. I set the setup up shown in the diagram above. First I put one set between the bases, added 100g and pulled the marg tub back 10cm and let go of it, and took down the distance it travelled. Then I added another 100g weight and did the same thing. I so added 100g after every consequence taken down and repeated the whole trial over three times.

Prediction V2:

If you add more weight to the marg bath and draw it back 10cm every clip, the bath will go a smaller distance every clip you add another weight. Because there will be more clash being created on the marg bath, this will do the bath to decelerate down more quickly and doing it to go a smaller distance.

Consequences V2:

Weight added ( g ) 1 ) distanced travelled ( centimeter ) 2 ) distanced travelled ( centimeter ) 3 ) distanced travelled ( centimeter ) Average distance ( centimeter )

V2 Conclusion

My consequences and chart show that my anticipations are right. If you add more weight to the marg bath and draw it back 10cm every clip, the bath will go a smaller distance every clip you add another weight. Because there will be more clash being created on the marg bath, this will do the bath to decelerate down more quickly and doing it to go a smaller distance. My graph has a curved tendency line which curves down and so easy starts to increase, this tells me, when there is more weight added it causes the bath to decelerate down emmet this causes it to go a less distance. This happens due to the sum of clash being created by the bath and the tabular array.

Method V3:

In this trial I tested to see if drawing the elastic set back different lengths, affected the distance that the marg bath travelled. I set the setup up shown in the diagram above. First I pulled the set back 1cm and recorded the consequence. Then I pulled it back 2cm and besides recorded the distanced it travelled. I did this until I reached 15cm. I besides added a fixed weight in the bath of 500g ; this helped to give more accurate consequences. I repeated the whole trial over three times.

Prediction V3:

I predict that if you pull the set back farther each clip, the bath will go a farther distance, this is because there is more force being added to the bath. There is a larger force because when the elastic set is stretched it springs back to its original length ; merely to a point, this is called the elastic bound. If the set passes the elastic bound the molecules in the set alteration form and do the set to alter length, and loses it strength and interruption. So the bath will go a farther distance when the set is pulled back further each clip, until it reaches its elastic bound!

Consequences V3:

V3 Decision:

My graphs and consequences show that my anticipation was right. I predicted that if you pull the set back farther each clip, the bath will go a farther distance, this is because there is more force being added to the bath. There is a larger force because when the elastic set is stretched it springs back to its original length ; merely to a point, this is called the elastic bound. If the set passes the elastic bound the molecules in the set alteration form and do the set to alter length, and loses it strength and interruption. So the bath will go a farther distance when the set is pulled back further each clip, until it reaches its elastic bound! My graph has a curved tendency line which curves up. This tells me that that the more force added ( set pulled back ) the farther distance the object ( bath ) travels. There is one point at the terminal of my graph, which drops somewhat. This is because the set may hold reached its elastic bound.

Evaluation:

My practical overall was rather accurate, I merely had a few anomalousnesss. These could hold been caused by let go ofing the bath, I could hold caught it with my finger ; besides when the bath stops, the weights could hold thrown it frontward somewhat this would hold affected the length but non by much. I could hold improved my practical by making more trials and by procuring the weights down in the bath decently. There were a couple inaccuracies in my practical, these were ; 1 ) when I put the weights in the bath I merely semi-secured them in. I should hold stuck them in firmly. 2 ) when I released the bath I might non hold allow it travel flawlessly.

If I had more clip I could hold done another experiment to see if altering the surface which the bath runs on..

Prediction exV:

I think if you change the surface from a smooth one to a unsmooth surface it would decelerate the bath down and do it to go a less distance because there would be more clash being created.
