Mechanics System 2

Code: 4861.29

An advanced low friction dynamics system to study elastic and inelastic collisions between carts

The Mechanics System 2 allows us to verify many kinematics and dynamics principles by using a low friction system.

The basic theory involves topics such as Newton’s Laws of Motion, Conservation of Energy and Momentum, Friction and many others.

EXAMPLE OF USE: Impulse – momentum theorem

Experimental verification of the theorem.

Using the Altay Mechanics System 2 we can induce a collision between two carts. The carts experience a force for a given amount of time resulting in its mass undergoing a change in velocity. Another way of expressing this is to say that this results in a change of momentum. There are four physical quantities which can be investigated: force, time, mass and velocity change. The force multiplied by the time is known as the impulse and the mass multiplied by the velocity change is known as the change in momentum. The impulse experienced by the cart is always equal to the change in its momentum.
This can be approximated as follows: F Δt = mΔv
