Oscillations

by Joe Wolfe
Oscillations
for 14-19 and upwards,
Lectures | 14-19 and upwards | 14 years ago | 1608 views
Rating:

Inertia and restoring forces can, with low friction or damping, lead to oscillations and resonance. We analyse the mechanics of vibrations.

Rotation
for 14-19 and upwards,
Lectures | 14-19 and upwards | 14 years ago | 1481 views

Momentum

by Joe Wolfe
Momentum
for 14-19 and upwards,
Lectures | 14-19 and upwards | 14 years ago | 1506 views
Rating:

p=mv. If external forces are zero, momentum is conserved. In collisions, energy may be conserved (elastic) or not (inelastic).

Centre of mass
for 14-19 and upwards,
Lectures | 14-19 and upwards | 14 years ago | 1841 views
Rating:

Energy and power
for 14-19 and upwards,
Lectures | 14-19 and upwards | 14 years ago | 1451 views
Rating:

The total work done on an object equals the increase in its kinetic energy. For conservative forces, we can define potential energy.

Weight and contact forces

by Joe Wolfe
Weight and contact forces
for 14-19 and upwards,
Lectures | 14-19 and upwards | 15 years ago | 1734 views
Rating:

Carefully distinguish mass and weight. Hooke's law quantifies deformation. Contact forces have normal and frictional components.

Life in Space
for 14-19 and upwards,
Discussions | 14-19 and upwards | 15 years ago | 1598 views
Rating:

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....

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.
