The main reason to perform the experiment is to orbit the principle of conservation of linear momentum. Here inelastic, elastic and dickens dimensional shocks be studied. The values of Length of Cart are stated below
Length of Cart (l) = 0.195m

Introduction:

Momentum depends on two quantities, mass and velocity. It is product of mass and velocity. It is a transmitter quantity so it is very important to break the vectors in two components. Here they are broken in x and y components In absence of external forces acting on a system, the total momentum of the system is conserved. Collisions between objects cornerstone result in the conversion of internal kinetic vim into some other form of energy. This persona of collision is called inelastic collision. This type of collision can deform the objects or objects aptitude stick to each other permanently. Other type of collision where kinetic energy and momentum both are keep is called elastic collision. Due to two factors preserved, there can be two types of results for this type of collision. Loss of energy is involved when two real objects are interacting with each other as no object can be totally elastic. The air deletion that was studied helps a lot to study both type of collisions because the air track provides a nearly frictionless rise due to which very minute amount of external forces act on the carts on the air track.



Magnets are inclined on the ends of both carts. For the first part of experiment, two types of magnets are attached on each end of carts which produces an elastic collision and freak each other. For the second part of experiment, the magnets are designed in such a way that the carts stick together at collision. Velocity is needed to find in both parts. The verbal expression used for velocity is as follows:

V = l / t * m

Here l= length (m), t = time (seconds) and m = mass (kg)

The formula for finding momentum is as follows:

P = m * v...If you want to get a full essay, bless it on our website: Orderessay
