What factors does momentum depend on?

What factors does momentum depend on?

Right Lines: Momentum, a quantity that’s a good measure of the motion of a body, depends on mass and on velocity. To work out which has the larger momentum you have to pay attention to both the mass and the velocity: →p = m × →v.

What two factors affect a vehicle’s momentum?

What two factors affect an object’s momentum? Momentum is affected by the mass of the object and its velocity (or speed).

What does change in momentum depend on?

The momentum change is dependent upon the velocity change; the object with the greatest velocity change has the greatest momentum change.

What is the momentum of the car?

Before the collision, one car had velocity v and the other zero, so the centre of mass of the system was also v/2 before the collision. The total momentum is the total mass times the velocity of the centre of mass, so the total momentum, before and after, is (2m)(v/2) = mv.

How does momentum depend on mass and velocity?

Mass and velocity are both directly proportional to the momentum. 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.

On what factors does force depend?

Solution: Factors on which moment of force depends are: (i) The magnitude of the force applied. (ii) The distance of line of action of the force from the axis of rotation.

How can we increase momentum?

What factors would affect the motion of objects in two dimensions?

Factors affecting the flight path of a Projectile are:

• Gravity.
• Air Resistance.
• Speed of Release.
• Angle of Release.
• Height of Release.
• Spin.

Which undergoes the greatest change in momentum?

The greatest change in momentum occurs when the baseball is caught and thrown back.

How can u increase the momentum of an object?

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.

How can momentum be transferred during a car collision?

Remember Newton’s third law—during a collision, two objects are acted upon by equal and opposite forces for the same length of time. This means that the objects receive equal and opposite changes in momentum, and the total momentum does not change. Momentum is transferred from one car to the other during the collision.

How is momentum conserved in a vehicle collision?

Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. In the collision between the truck and the car, total system momentum is conserved.

How to calculate the change in momentum of a car?

Using the definition of impulse, the change in momentum of car 1 is given by Δ p1 = F1 Δ t , where F1 is the force on car 1 due to car 2, and Δ t is the time the force acts (the duration of the collision). Intuitively, it seems obvious that the collision time is the same for both cars, but it is only true for objects traveling at ordinary speeds.

How does the stopping distance of a car depend on its momentum?

IF the forces on two cars are equal then the greater the kinetic energy the greater the distance before stopping. But there will be a relationship to the momentum because momentum and mass are both related to the kinetic energy. But force is often dependent on mass, directly or indirectly.

What kind of things does momentum depend on?

So, to answer your original question, momentum can depend on a very large number of things, depending on the context and your interest, including: (1) mass, (2) velocity, (3) relativistic energy, (4) matter wave frequency, among others.

Is the momentum of a car at rest zero?

So, to be honest, the answer to your question depends on whom you ask. For the bystander, the car’s momentum is zero as he observes it to be at rest, but for some other person, say a driver in a car moving out from the parking lot, the car may appear to be in motion, and hence, have non-zero momentum. 692 views.
