Is momentum conserved when a ball is thrown upward?

Momentum is still conserved. You have to consider the momentum of the whole system. The momentum of the Earth experiences equal and opposite changes relative to the ball, and the center of mass of the system (Earth plus ball) doesn’t move at all.

When a body is thrown upwards the magnitude of its momentum decreases at first and then increases Does this defy the law of conservation of momentum?

A ball in thrown up. The magnitude of its momentum first decreases and then increases. Does this violate the conservation of momentum principle.

When a ball is thrown vertically upwards why does its velocity decrease?

When a ball is thrown vertically upwards, its velocity goes on decreasing. As the velocity of the ball goes decreasing, its kinetic energy also goes decreasing and its potential energy starts increasing. And when the velocity becomes zero, its kinetic energy is zero and converted into its potential energy.

In which situation does the law of conservation of momentum apply?

For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

When a ball is thrown upwards its momentum first decreases?

When a ball is thrown upwards, its momentum first decreases and then increases. Is conservation of linear momentum violated in this process? No, the momentum conservation principle is not violated. Infact, this principle cannot be applied to this case as external force due to gravity is involved.

When a ball is thrown upward its momentum first increases and then decreases?

Here in this case of throwing ball upwards, the ball is in action of many external forces like weight, air drag, etc which leads to change the momentum of the ball with time. Hence, law of conversation of momentum is holds only when no external force acting on the body.

When a ball is thrown upwards its momentum first decreases and then increases?

When a ball is thrown vertically upwards its velocity?

When a ball thrown vertically upward it’s velocity goes on decreasing it’s potential energy increases because potential energy increases when it is raised to a height against gravity which is known as the gravitational potential energy . That’s why it’s kinetic energy becomes 0.

When a ball is thrown vertically upwards its velocity keeps on decreasing what happens to its kinetic energy when it reaches the maximum height?

When a body is thrown vertically upwards against the force of gravity, its kinetic energy keeps on decreasing as its velocity decreases. At the maximum height, kinetic energy becomes zero, as the velocity of the body becomes zero at this moment.

When a ball is thrown upward its momentum first decrease and then increase is the conservation of momentum violated in this process?
