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. |
