Newton’s laws of motion

by Joe Wolfe
Newton’s laws of motion
for 14-19 and upwards,
Lectures | 14-19 and upwards | 15 years ago | 1415 views
Rating:

F=ma (laws 1&2). Forces come in pairs that add to zero (3). Newton's laws apply in inertial frames of reference. Some common approximations made in applying them.

Motion with constant acceleration (kinematics)

by Joe Wolfe
Motion with constant acceleration (kinematics)
for 14-19 and upwards,
Lectures | 14-19 and upwards | 15 years ago | 1733 views
Rating:

Kinematics quantifies motion without explaining the causes of it. Here we study accelerations that are zero, positive or negative.

A Quantum Gas

by Slobodan Danko Bosanac
A Quantum Gas
for 22 and upwards,
Lectures | 22 and upwards | 16 years ago | 2116 views
Rating:

The quantum gas is an extreme state of an ensemble of atoms when their de Broglie wave length is of the same length as the size of the container. The ways of achieving this state are described and also how its temperature is defined.
