# Often asked: When a constant force acts on an object, what does the object’s change in momentum depend upon?

## What does change in momentum depend on?

Resulting change in momentum depends on both force and time during which the force is applied. Impulse is what an object can provide or what it can experience; an object doesn’t have impulse, whereas an object has momentum.

## Does change in momentum depend on mass?

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.

## Does momentum depend on force?

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.

## What factors affect how much an object’s momentum changes?

What factors affect an object’s momentum? Mass, speed and direction (if direction is important). What factors affect how much an object’s momentum changes? The change in momentum depends on the force that acts and the length of time it acts.

## What is a change in momentum called?

This change in momentum is called impulse, and it describes the quantity that we just saw: the force times the time interval it acts over. The greater the impulse, the greater the change in momentum.

## 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.

## What is the relationship between mass and momentum?

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object’s mass and directly proportional to the object’s velocity.

## Can change in momentum be negative?

Momentum is a vector and has the same direction as velocity v. Since mass is a scalar, when velocity is in a negative direction (i.e., opposite the direction of motion), the momentum will also be in a negative direction; and when velocity is in a positive direction, momentum will likewise be in a positive direction.

## What is the relationship between force and mass at constant acceleration?

It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied. If the same force is applied to two objects of differ- ent mass, the heavier object has less acceleration than the lighter object (Figure 1).

## What is the difference between momentum and force?

Momentum is amount of motion in a moving body, whereas force is an action of push or pull. Force changes momentum of a body. Force does not change for constant acceleration whereas momentum changes. Momentum increases with time for an applied force.

## What is the difference between momentum and velocity?

What is the difference between momentum and velocity? Momentum is dependent on mass, and velocity is independent of mass. The momentum is conserved in a closed system, but the velocity is not conserved. An external force is always required to change the velocity, but momentum can be changed by changing mass.

## Which motion does not require force to maintain it?

Answer. The one type of motion that can be maintained in the absence of an interfering force is the uniform linear motion. Linear motion is a type of motion in which the object in motion moves along a straight line an is uni-dimensional.

## What can affect momentum?

The direction of the momentum vector will be the same as the velocity. 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 two factors affect impulse?

1 Answer. The two main factors are insulation by the myelin sheath and the diameter of the axon.

## What two factors affect acceleration?

The acceleration of an object depends on the mass of the object and the amount of the force applied to it. It states that the acceleration of an object increases with increased force and decreases with increased mass.
