What is overall momentum of a system after collision if there is no external force acting on it?

There are no external forces; the system is isolated. The total system momentum would be expected to be conserved.

What happens when no external force acts on a system?

The principle of conservation of momentum states that in an isolated system of objects on which no external force is acting, the initial momentum of the objects is equal to the final total momentum of the objects, that is, the total momentum of the system remains conserved.

When external force applied on a body is zero the momentum of body will be?

Force, F = dp /dt ( rate of change of momentum). Therefore, only when the momentum is constant, will the acting force be Zero.

When no external force is acting on a particle the centre of mass of the system is?

The centre of mass of such a system remains at rest.

What is the momentum of the system after the collision?

After the collision, the total system momentum is the combined momentum of the brick and the cart. Since the brick and cart travel at the same velocity after the collision, the momentum is simply the sum of their masses multiplied by their velocity.

When no external forces act kinetic energy is conserved?

If there are no external forces acting on this system (consisting of the two masses) the total momentum of the system is conserved. The first class of collisions we will discuss are the elastic collisions. Collisions are called elastic collisions if the total kinetic energy of the system is conserved.

When external force acting on a system have a zero resultant then the centre of mass has zero?

If the external forces acting on a system have zero resultant, the center of mass. must not move. must not accelerate.

When no external force acts on a body what will be its acceleration?

If external force on a body is zero, its acceleration is zero.

When an external force is applied at the centre?

(A) : When an external force is applied at the centre of mass o a system of particles then it undergoes translatory motion only.

When no external force acts on an object the physical quantity that remains conserved is 1 point a velocity b momentum C Acceleration D force?

Answer: If no external force applied then acceleration will be zero ,so velocity remain conserve .

What happens to linear momentum when there is no external force?

If no external force acts on a closed, isolated system of particles, the total linear momentum P of the system cannot change. If the component of the net external force on a closed system is zero along an axis component of the linear momentum along that axis cannot change.

What happens when there is no external force on the system?

If no external force acts on a system of particles, then the centre of mass will not move in any direction. If net external force is zero, then the linear momentum of the system changes. The acceleration of centre of mass is zero and so it will continue to move with its initial velocity.

Why is linear momentum constant in a closed system?

The momentum is constant if no external forces act on a closed particle system. Internal forces can change the linear momentum of portions of the system, but they cannot change the total linear momentum of the entire system. Isolated: the net external force acting on the system is zero.

What happens to the center of mass when textual Forces Act?

When a body or a connection of particles is acted on by textual forces, the center of mass moves just as though all the mass were concentrated at that point and it were acted on by a net force equal to the sum of the external forces on the system. This result may not sound very impressive,…
