What affects momentum change?

What affects momentum change?

Momentum change depends on velocity change and the velocity change is greatest in case B (as stated above). Observe that each of the collisions above involve the rebound of a ball off a wall. Observe that the greater the rebound effect, the greater the acceleration, momentum change, and impulse.

What force affects momentum?

You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum. A large, fast-moving object has greater momentum than a smaller, slower object.

What characteristics of an object affect its momentum?

The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.

Which factor would not change the momentum of an object?

Direction. Notice that momentum does not just depend on the object’s mass and speed. Velocity is speed in a particular direction, so the momentum of an object also depends on the direction of travel.

What are the two factors affecting acceleration of an object?

The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

Does weight affect momentum?

Weight is the measurement of resting inertia and momentum is the measure of inertia at a certain velocity. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

What factors affect the momentum of an object?

Answer- two factors affect the momentum, namely, the mass of the object and its velocity. (Velocity, not speed, as the direction is an important part of momentum given that it is a vector quantity). At relativistic speeds ( getting on for the speed of light) then gamma comes into play.

How does momentum change in quantum mechanics?

In Quantum Mechanics. Anything that changes the velocity v and/or mass m of your object will change its momentum. Note that velocity v is a vector, so if it changes in magnitude and/or direction then the momentum of the object will also change. That being the case, any external force can change the momentum. The mechanism is as follows.

Why are mass and velocity important in the momentum equation?

Both variables – mass and velocity – are important in comparing the momentum of two objects. The momentum equation can help us to think about how a change in one of the two variables might affect the momentum of an object. Consider a 0.5-kg physics cart loaded with one 0.5-kg brick and moving with a speed of 2.0 m/s.

What is the difference between impulse and momentum?

In summary, I try to say that impulse is the multiplication of applied force and time interval it applied. Impulse is also a vector quantity having both magnitude and direction. It has the same direction with applied net force. Impulse and momentum are directly related to each other.
