Life in Space
Helen Sharman, the UK's first astronaut, gives a vibrant account of her personal experience of life in space using models and film to illustrate the key scientific concepts involved in spaceflight. Among other things she discusses the way Newton's Th....

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.

In simple harmonic motion, displacement, velocity and acceleration vary sinusoidally with time, but with different phases.
More details | Watch nowCircular motion
Uniform circular motion: angular displacement and velocity are introduced and centripetal acceleration is determined.
More details | Watch nowProjectile motion
Motion with uniform acceleration, such as in a uniform gravitational (or electric) field is projectile motion, analysed here with examples.

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

A description and demonstration of the way in which craters formed by dropping objects into sand can be linked to some elementary physics

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.
