What is the magnitude of force acting on a body moving with constant velocity?
Certainly not. An object has momentum on account of its motion, which depends on its mass and its velocity. Force may be involved in the object's motion, but doesn't need to be. If we let the discussion become somewhat flabby, we can imagine a constant force applied to an object, and asked what happens to the object's momentum. An object with a constant force acting on it exhibits constant acceleration in the direction of the force. In that situation, the object's speed, and therefore its momentum, are proportional to the time the force continues to act on it.
What is the difference between net force and newtons third law?
Net force is the vector sum of all forces on a body. Newtons third law relates net force to change in momentum with time.
Newton's first law is a special case of the second law Explain?
Newton's second law states that the rate of change of momentum of a body is equal to the resultant force on the body and is in the same direction as the resultant force. Thus, it also implies that when the resultant force on a body is zero, the rate of change of momentum is zero, and if it concerns a body of constant mass, the acceleration is zero. This is Newton's first law, which states that 'any body continues in its state of rest or uniform motion in a straight line unless a resultant force acts on it to cause it to accelerate'.
What is meant by momentum?
A body's resistance to change position or course.
How do you describe newton's 2nd law?
Newton's second law states the rate of change of momentum of a body is directly proportional to the resultant force on the body and is in the same direction as the resultant force.
How can you relate a force with the change of a momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How can you relate the force with the change of momentum of a body?
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.
How can you related of force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
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 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.
What happens to the momentum of a body acted on by an external force?
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.
Initial momentum of a body is 200kgms and it changes to 500kgms in seconds on application of force find the change in momentum and rate of momentum and force applied?
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.
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.
How do forces cause a change in an object's momentum?
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.
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.
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
Can kinetic energy cause changes?
kinetic energy can change momentum of the body if any external force exist
