effect on apparent weight as a body accelerates . for eg: if a person standing on weighing machine sits down with a jerk, wat happens???? wat will be the whole graph if the person sits down with a jerk and then remains sitting

wat will happen in the revierse case

Its simple sweet,

When some1 sits with a jerk, there is change in momentum and hence force in downward direction.

That is for the only the small time.

But when the body is seated only the body weight is the force on the machine.

as the person sits down wid a jerk there is a change in momentum .....dis leads to ,, impulse .. for a certain time ....

as far as the graph is cocerned ,,,,,,in both the graphs there will be sudden "spike" for time=dT the the graph will regain it's shape ....

plzzzzzz rate dis ????

When a person is sitting with a jerk. His velocity in downward direction first increases and then decrease. So there is first a downward acc and then an upward acc. So apparent weight will first increase and then decrease and finally willbe equall to true weight
