If the mass of a moving object decreases from 100 grams to 25 grams, what happens to its momentum? a. its reduced 1/4 of the original momentum b. its reduced 1/2 of the original momentum c. not affected by change in mass d. becomes 4 times the orignal momentum

The correct answer is c. not affected by change in mass

The law of conservation of momentum states that, for an isolated object (=zero net external force acting on it), the momentum of the object is conserved.

As a result, if there are no external forces acting on the object in the problem, its momentum will not change even though its mass changes. In fact, the momentum is given by the product between mass and velocity:

therefore, when the mass of the object decreases by a factor of 4, the velocity will increase by a factor of 4, keeping the momentum of the object constant.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500
