Reducing friction with ball bearings
Find two tin cans that have a deep groove approximately the top, such as paint cans. Lay marbles in single groove and invert the other can over the marbles to form a ball bearing. Place a book on top and note how simply the demonstration bearing turns. Oil the marbles and it will turn still more easily.
‘q' is a path function. Under what situations it will be a state function? Define and illustrate heterogeneous and homogenous systems with examples.

A 35-kg child is riding on a swing that rises to a maximum height of 0.80 m. Neglecting friction, what is the child's gravitational potential energy at the top of the swing?
Snell's Law: The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from one medium to another medium. That is Sini/Sinr
