Newton's Second Law was originally formulated as: F=dm/dt. That is, the force is proportional (or equal, if the correct units are used) to the rate of change of momentum. The more force, the faster will the momentum change.
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
The force acting on a body is directly proportional to the rate of change of its momentum, as given by Newton's second law of motion (F = dp/dt). When a force is applied to a body, it results in an acceleration, causing a change in the body's momentum. The greater the force applied over a period of time, the larger the change in momentum of the body.
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
Force is directly related to the change in momentum of a body, as described by Newton's second law of motion. The force acting on an object causes a change in its momentum by accelerating or decelerating it. The greater the force applied, the greater the change in momentum experienced by the body.
The impulse experienced by a body is equal to the change in its momentum. This means that when an external force is applied to an object, its momentum changes, causing the object to experience an impulse in the direction of the force applied.
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
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.
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.
If the force opposes the motion, it will reduce the velocity and the momentum of the body will decrease. If the force is in the direction of the motion, the velocity will increase and the momentum will increase.
Darn ! I was reading this and really getting into it and planning to tackle it. But you left out how many seconds ??? The change in the body's momentum is +300 kg-m/s . Tell us how many seconds, and we'll answer your other questions too.
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.
