Impulse and momentum

Impulse and momentum collision

 

Objective:

In this experiment our objective is to compare the impulse on a cart and its momentum change. The motion of the cart will be studied with a CBR when the cart collides with a force probe. The force probe is connected via a CBL or a LabPro to a graphing calculator. The CBR is connected to another graphing calculator. Collected data from both probes will be stored in the two graphing calculators and can be analysed either with a calculator or a computer, using previously collected data.

Nicolas Malebranche (1638-1715) was crippled all his life with a deformed spine and this meant that he did not attend school in the usual way but was educated at home to the age of sixteen. Then he studied philosophy and theology at the College de la Marche. He went to the Sorbonne in Paris, again intending to make theology his life's work. Malebranche read Descartes' Traité de l'homme and this turned him towards a study of mathematics and physics. At first Malebranche's ideas of the physical world followed closely those of Descartes and were based on a belief in a rational geometrical world. He based his laws of motion on the abstract laws of collisions between idealised solid objects. However Leibniz tried, with some success, to persuade Malebranche that the laws of motion were not entirely mathematical laws but were the consequence of God's creation. He basically believed that if two spheres collided then there was no force which changed the direction of their motion. Rather he saw the collision as an occasion for God to act and since a perfect God would act in the simplest way then the result would always result in the same change in motion. Malebranche's other work includes research into the nature of light and colour.
