Testing The Forces Affecting The Distance A Margarine Tub Travels. Introduction: We are testing for actions or influence that accelerates, or changes the velocity of, an object. An object experiences a force when it is pushed or pulled by another object. For example, shoving a stationary ball applies a force that causes the shopping ball to accelerate. Also a dropped ball accelerates towards the ground because of the presence of the gravitational force; electrical charges …showed first 75 words of 1395 total…

If I had more time I could have done another experiment to see if changing the surface which the tub runs on.. Prediction exV: I think if you change the surface from a smooth one to a rough surface it would slow the tub down and cause it to travel a less distance because there would be more friction being created.
