Simple steelyard (reading to 100 g)
The pan is made from cardboard, and is formed like a funnel. It is fixed to a beam made of a triangular-shaped lamina in ply- wood or 'Perspex'.
The beam tapers from 2 cm at the extreme end to 5 cm near the pan. The pivot, which can be a strong darning needle, is driven by the beam at a point about 5 cm from the pan and 2 cm from the top edge. Some part of the beam or pan can be cut away to make it balance
A simple harmonic oscillator of amplitude A has a total energy E. Determine (a) the kinetic energy and (b) the potential energy when the position is one-third the amplitude. (c) Fo
It is the property of changing readily from a solid or liquid to a vapour. It is the speed that a chemical compounds evaporates. Higher volatility indicates faster evaporation.

The opposition offered to the circular motion of bodies like sphere, disc, ring, cylinder etc. on another surface is known as rolling friction.
Car Rear Ends Truck Collisions among objects are governed through laws of momentum and energy. While a collision occurs within an isolated system, the total momentum of the sys
If the speed of light were smaller than it is, would relativistic phenomena be more or less conspicuous than they are now? All else being similar, involving the rates of the ch
