When comparing the momentum of two moving objects, which of the following is correct?

When comparing the momentum of two moving objects, which of the following is correct? The object with the higher velocity will have less momentum if the masses are equal. The more massive object will have less momentum if its velocity is greater.

What happens to the momentum of two objects which interact?

Momentum is conserved in the collision. Momentum is conserved for any interaction between two objects occurring in an isolated system. This conservation of momentum can be observed by a total system momentum analysis or by a momentum change analysis.

How do you compare momentum?

To compare the momenta of two objects, simply find the momenta of each. The tricky part about this is that sometimes you find that a small object can have a larger momentum than a large object. This occurs when the smaller object has a larger velocity.

Which of the following situation is an example of a significant change in momentum?

Which of the following situations is an example of a significant change in momentum? A tennis ball is hit into a net. … Two objects move separately after colliding, and both the total momentum and total kinetic energy remain constant.

What are the 2 factors that affect momentum energy of motion?

Putting “Momentum” in Conceptual terms: Two factors affecting momentum is the mass and velocity of the object. An object that has a low velocity and a small mass produce minimal momentum because it would take a small force and/or time to stop it.

What happens when two objects collide?

Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).

Is momentum always conserved?

Collisions. In collisions between two isolated objects Newton’s third law implies that momentum is always conserved. … In collisions between two isolated objects momentum is always conserved. Kinetic energy is only conserved in elastic collisions.

What is the relationship between mass and momentum?

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.

What unit is momentum in?

kg
The units for momentum would be mass units times velocity units. The standard metric unit of momentum is the kg•m/s.

Does Momentum have direction?

Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion.

How do you calculate change in momentum?

How to Calculate Change in momentum? Change in momentum calculator uses change_in_momentum = Mass*(Initial Velocity at point 2-Initial Velocity at point 1) to calculate the Change in momentum, Change in momentum is the quantity of motion that an object has. If an object is in motion (on the move) then it has momentum.

What’s the difference between momentum and kinetic energy?

Some people think momentum and kinetic energy are the same.

They are both related to an object’s velocity (or speed) and mass, but momentum is a vector quantity that describes the amount of mass in motion. Kinetic energy is a measure of an object’s energy from motion, and is a scalar.

Can a lighter object have more momentum than a heavier one how?

Question: Can A Lighter Object Have More Momentum Than A Heavier One? … No, Because Momentum Is Independent Of The Mass Of The Object.

What are the factors that affect momentum?

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

What factors affect angular momentum?

Angular momentum depends on the rotational velocity of an object, but also its rotational inertia. When an object changes its shape (rotational inertia), its angular velocity will also change if there is no external torque.

How is impact force related to momentum?

Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum. They are related by the fact that force is the rate at which momentum changes with respect to time (F = dp/dt). Note that if p = mv and m is constant, then F = dp/dt = m*dv/dt = ma.

Do objects stick together in an inelastic collision?

People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision. Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved.

What happens when two objects at different temperatures touch?

If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter to the colder object until equilibrium is reached and the bodies reach thermal equilibrium (i.e., they are at the same temperature).

Why is momentum conserved?

The conservation of momentum is simply a statement of Newton’s third law of motion. During a collision the forces on the colliding bodies are always equal and opposite at each instant. These forces cannot be anything but equal and opposite at each instant during collision. … Therefore the momentum is always conserved.

Why is momentum not conserved?

The vertical component of the momentum is not conserved, because the net vertical force Fy–net is not zero. In the vertical direction, the space probe-Earth system needs to be considered and we find that the total momentum is conserved.

How do you know if momentum is conserved?

The momentum of an object will never change if it is left alone. If the ‘m’ value and the ‘v’ value remain the same, the momentum value will be constant. The momentum of an object, or set of objects (system), remains the same if it is left alone. Within such a system, momentum is said to be conserved.
