## Is momentum conserved in a closed system?

1) Closed system – A closed system does not interact with its environment so there is no net external impulse.

The total momentum of a closed system is conserved.

That is, the total momentum of the system remains constant..

## 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.

## Can any object have momentum if its momentum is zero?

Notes:Momentum is mass in motion, and any moving object can have momentum. The change in the momentum of an object is equal to its momentum. Impulse is the amount of force multiplied by the time interval.

## 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 an object have mechanical energy if its momentum is zero?

1 Answer. Since, mechanical energy is the sum of kinetic energy and potential energy. And as given that, momentum of the body is zero, it means velocity of the body is zero, so it has kinetic energy equals to zero. … So, even if the momentum of the body is zero, it may have mechanical energy.

## Can a body have momentum without kinetic energy?

So, if the Kinetic energy is zero, momentum will be zero. Hence, a body cannot have momentum without having energy.

## Is it possible to have 0 velocity and still be accelerating?

Yes, an object can have zero velocity and still be accelerating simultaneously.

## What is linear momentum do object have linear momentum when its velocity is zero?

Answer. Answer: p=mv. if v becomes 0 overall p also becomes 0.

## Can an object move with zero velocity?

Yes, it’s possible to have zero speed while accelerating, but only for an instant. … Acceleration is the rate at which an object’s speed and direction are changing with time, so whenever an object passes through zero speed as it reverses directions it has a non-zero acceleration but a speed of zero.

## Which if either has greater momentum a 1 kg ball moving at 2 m/s or a 2 kg ball moving at 1 m s?

Which if either has a greater momentum: a 1-kg moving at 2m/s or a 2-kg bad moving at 1 m/s. Which has a greater kinetic energy? Same momentum, but different KE. The 1-kg ball traveling at 2 m/s has a greater KE.

## Does an object having energy always has momentum?

Ch 8 Think & Explain Answers: Yes, an object with momentum always has energy. If the object has momentum (mv) it must be moving, and if it is moving it has kinetic energy. No, an object with energy does NOT always have momentum. … Since this object’s velocity = 0, its momentum is zero.

## Is angular momentum conserved?

The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.

## What is the momentum of an object zero?

An object can have zero momentum when either its mass or its velocity is zero. Since, negetive mass doesn’t exist, the velocity should be zero and thus, the object must be at rest.

## Can a body have an acceleration with zero velocity?

Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up. At the peak point its velocity becomes 0 but still accelerates due to gravity.

## Can an object with negative acceleration have a positive velocity?

An object which moves in the positive direction has a positive velocity. … If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).
