What happens when body exerts force over time?
it is known as impulse Impulse means the momentum change OS the body Imp =m(v2-v2) if divide both sides by time impulse /time= m (velosity change/time) = ma =force hense impulse = force*time
What is an impulse in scientific terms?
Impulse is force x time where the assumption is that the force is high and the time is short. Since force is rate of change of momentum of a free body, then impulse amounts to a sudden change of its momentum.
What is impulse in physics?
Einstiens law of relativity. That does not relate to impulse. Impulse equates to a change of momentum, usually thought of as for a very short time, but doesn't have really to be so short. Now since force = mass times acceleration =m.dv/dt, you can write that as d/dt of mv, so force =rate of change of momentum So force times time (or its integral over time, which is the same thing) must equal simply the change of momentum. In the case where it a very short time, all that happens is that the momentum changes instantaneously.
How is weight a force?
because it is experienced by pull of earth.weight of a body is equal to force by which earth pulls body towards its centre
What is the force applied over a period of time is required to give a stationary object momentum called?
impulse
What is a direction of impulse?
impulse is equal to force which is acting on the body and ti me in small interval which is equal to momentum.so impulse is equal to change in momentum and direction of impulse is consider the direction of force and change in momentum.

Distinguish between impulse and momentum which is force x time and which is inertia in motion?
Impulse is equal to the change in momentum: definition of impulse is Force x time. When a force is applied to an object for a certain amount of time its momentum (mv) will increase because it is accelerating due to the force on it. Force x time = the change in MV (change in momentum) This is just a restatement of Newtons law F=MA it is actually derived directly from F=MA

Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
What is an air bag in car how it saves driver from injury?
Impulse gives the impact on the body. Impulse is measured by the change in momentum. And rate of change of momentum is force which causes harm on the body. So as we extend the time duration for any change in momentum force is terribly reduced and hence no severe impact. Hence safe journey with a air bag behind the driver.
Can a moving object have impulse in itself?
yes moving objects have impulse
What force is on a body that are equal in size and opposite in direction and do not change the motion of the body?
9.81
What is the force applied over a period of time is required to give a stationary object momentum called?
impulse
How fast does a nerve impulse travels?
It 200 miles per hour And it can probally be in meters too.
