# Question: Does Momentum Depend On Force?

## On what factors does the momentum depend?

Both mass and velocity 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 is difference between momentum and velocity?

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. … The equation illustrates that momentum is directly proportional to an object’s mass and directly proportional to the object’s velocity. The units for momentum would be mass units times velocity units.

## Can momentum be lost to friction?

Nope. The momentum lost from an object due to friction is momentum gained by the thing the object is rubbing against.

## What unit is momentum in?

The standard units for momentum are k g ⋅ m / s \mathrm{kg \cdot m/s} kg⋅m/sk, g, dot, m, slash, s, and momentum is always a vector quantity. This simple relationship means that doubling either the mass or velocity of an object will simply double the momentum.

## Why is momentum not a force?

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 the object’s velocity and therefore changing its momentum.

## What is momentum in real life?

Momentum in a simple way is a quantity of motion. … If an object does not move then it has no momentum. However, in everyday life it has an importance but many people didn’t recognize it. Momentum is just about every activity that involves motion. It is an essential concept of physics.

## Does speed affect 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.

## Can momentum be lost?

Provided that there are no net external forces acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision. If there are only two objects involved in the collision, then the momentum lost by one object equals the momentum gained by the other object.

## Does momentum depend on inertia?

Momentum is a vector quantity as it the tendency of a body to remain in motion. Inertia is a scalar quantity as it is the resistance offered by the body to any change in its velocity. … Momentum depends on mass and velocity. Inertia depends only on mass.

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.

## Is momentum proportional to force?

The rate of change of momentum of an object is directly proportional to the resultant force applied and is in the direction of the resultant force.

## 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.

## Is momentum a energy?

Energy in a system may take on various forms (e.g. kinetic, potential, heat, light). destroyed. Objects in motion are said to have a momentum. It is a product of the mass of an object and its velocity.

## Is momentum a vector or scalar?

The momentum of a body is a vector quantity, for it is the product of mass, a scalar, by velocity, a vector.

## Does momentum depend on acceleration?

Acceleration depends on velocity change and the velocity change is greatest in case A (as stated above). … Momentum change depends on velocity change and the velocity change is greatest in case A (as stated above).

## Does inertia depend on mass?

The inertia of an object is a measure of its resistance to a change in the state of its motion. It is solely dependent on the mass of the object, with more massive objects having larger inertia and a greater tendency to resist changes to their motion.

## Is momentum the same as acceleration?

Momentum Conservation and Newton’s Laws Recall that acceleration is rate of change of velocity, so we can rewrite the Second Law: force = mass x rate of change of velocity. Now, the momentum is mv, mass x velocity. This means for an object having constant mass (which is almost always the case, of course!)

## Why do we use momentum?

Momentum is an important consideration in physics because it describes the relationship between speed, mass and direction. Momentum describes the force needed to stop objects and to keep them in motion. … Momentum can also be used to predict the resulting direction and speed of motion of objects after they collide.

## Which object has the greatest acceleration?

Object C has the greatest acceleration. It is the only object with an acceleration. Accelerated motion on a p-t graph is represented by a curved line.

## Why is P used for momentum?

Originally Answered: Why do we use (p) as the momentum symbol? It is because m was already taken for mass , for that matter all the other letters were taken. p is used because the word impetus formally in place ofmomentum comes from the latin, petere, hence we get p.

## Is rate of change of momentum force?

The rate of change of momentum of an object is directly proportional to the resultant force applied and is in the direction of the resultant force. The resultant force is equal to the rate of change of momentum.
