Question

what are the products of destructive distillation of coal and their uses

Answer 1

According to Newton's First Law: An object at rest stays at rest and an object in motion stays in motion without changing speed and direction until it's acted by a force. All objects are inert. Inertia is the appearance that body wants to keep condition in which it was before force treated.
Examples:
1. Bus passengers stays in rest while the bus is in rest. When bus gets velocity and starts moving, at the first passengers pull back because they are inert and "want" to stay in rest. Also, if bus starts breaking and slows, passengers lean forward in the direction of movement as they "want" to keep moving with velocity had.
2. To prevent whiplash injuries during rear-end collision in car there are headrests placed
3. If you shake a branch of a tree fruits will fall down because of inertia of the rest.

Answer 2

Coke, coal gas, gas carbon, coal tar,ammonia liquor, and "coal oil" are examples of commercial products historically produced by the destructive distillation of coal.
