Why Is Momentum Not Always Conserved? Momentum is not conserved if there is friction, gravity, or net force (net force just means the total amount of force). What it means is that if you act on an object, its momentum will change. This should be obvious, since you are adding to or taking away from
What Is The Momentum Of A Rocket Before Flight? Answer: Before launch, the rocket is at rest on the launch pad, so its momentum is zero. When the rocket engines fire, burning gases are expelled from the back of the rocket. By virtue of the law of conservation of momentum, the total momentum of the
In Which Situation Is The Angular Momentum Of A System Of Objects Conserved? The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero. Under what condition is the angular momentum of
Does Momentum Travel Around A Curved Piece Of Metl? When a moving object collides with a stationary object of identical mass, the stationary object encounters the greater collision force. When a moving object collides with a stationary object of identical mass, the stationary object encounters the greater momentum change. Are there any exceptions for the
Does A Moving Object Have Impulse Or Does It Have Momentum? Does a moving object have impulse or does it have momentum? impulse is the product of the average force and the short time interval for which it acts and causes a change in momentum of a body, A moving object can experience an impulse
