Class practical: Friction spoils the downhill and uphill experiment of a rolling ball on a curved track. This is Galileo's...

Practical Activity 14-16

Demonstration: When a pendulum is displaced, it stores energy gravitationally due to its increased height. When subsequently...

Practical Activity 14-16

Demonstration: Machines let us move a large force using a small one, but they do not multiply energy. This demonstration...

Practical Activity 14-16

Demonstration: Energy transfers in a simple pendulum illustrate the principle of conservation of energy.

Practical Activity 14-16

It is no real surprise that the world is richer and more complicated than science textbooks make it appear. And it is no...

Practical Activity 14-16

Demonstration: In elastic collisions the energy stored kinetically is conserved. In inelastic collisions it is not. But where...
