Question

take 6 sample objects like a stone, a plastic
ball an empty box, a full box , a'ball
made of paper, a Steel glass, a pencil
Apply almost equal amount force to each
of them and with help of a watch observe
the amount of time taken by
each abject
separately to come to complete rest. Make
a tabular format of time taken by each
object.
​

Answer 1

Answer:

The lesser weight objectshave taken less time than higher weight objects.So force is directly proportional to weight

Answer 2

Explanation:

since

F = ma

=> a = F/m..........................(1)

=> acceleration is inv.prop. to mass

also u = -at

=> t = -u/a ............ ... .............(2)

since F and u are same for all objects

=> t = (-u/F) m

=> time is proportional to mass

=> time taken increased with increases mass
