Collision

PHY 302


Lab 6: Collisions



Objectives of the Experiment :
Investigation of striking with varied masses .

Materials Used :
* Track
* 2 deposit detectors : these ar used to sense the force and the are specialized for the quantity of interrogation parameters.
* 2 carts
* Data studio which is used to canvass the change in momentum of the cart with the integral of the careful force vs. time graph

The setup :

Theory :
When an butt strikes a barrier, the force on the object varies as the collision
occurs. Changes in the momentum of the object (the impulse) can be calculated in
twain ways:
Using the velocities before (vi) and after (vf) the collision:
?p = mvf mvi
Using the net force and time of impact: ?p= ? Fdt = Fnet ?t
It is possible for the object to undergo the same change in momentum whether it is
involved in an abrupt hard collision or a cushioned collision. We want to determine
the difference in the midst of how a hard or squashy collision affects the force felt by the object.





Hypothesis:
When increasing the mass of the cart, the % geological fault between the impulse and the change in the momentum decreases.
passion is constant for a hard or a soft collision, ?t varies: shorter for a hard collision and longer for a soft one.

Procedure :
* colligate the interface to the computer
* Connect the motion sensor to the interface
* Place the dynamic nerve tract on a horizontal surface
* Raise the remainder of the dynamic trail that is opposite to the end with the force sensor about 1.5 cm so the cart will draw approximately the same speed for each trial.
* Place the motion sensor at the raised end of the dynamics track so it can measure the motion of the cart .
* evaluate the mass of the cart . Record the mass value in the report .
* Prior to each data run , narrow the tare button on the side of the force...If you want to reach a full essay, order it on our website: Ordercustompaper.com
