COnvervation of momentum during a collision
Questions
1. Explain how the use of the sloping chipboard ‘compensates for friction’
The use of the sloping chipboard compensates for the friction in the experiment as it increases the acceleration on the cart due to gravity and if placed on the right angle it will correctly compensate for the speed lost in friction.
2. Why should the amount of Velcro used be just enough to make the trolleys adhere after the collision?
The amount of Velcro used should be enough to keep the trolleys together after the collision but not so much that it will absorb the impact of the collision and reduce the final momentum resulting in an unusable attempt.
3. Discuss any differences in total momentum before and after the collision
There were small amounts of differences in momentum before and after the collision, this can be related back to random and systematic errors throughout the experiment such as the equipment being slightly off. There is also energy lot through the form of sound and friction of the wheels.
Introduction:
This experiment explores the conservation of momentum and energy in the controlled environment of a science lab. The conservation of energy and momentum plays an important role in physics and their consequence of f fundamental symmetries of nature
Variables:
The variable of this practical is the initial momentum of trolley A before it collides with trolley B.
Hypothesis:
My hypothesis is that the law of conversion of momentum (L.O.C.O.M.) is correct and that the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
Equations:
p=mv
