Why is the change of momentum zero in an isolated system?
In an isolated system, the total external forces acting on the system are zero. Since momentum is a vector quantity that depends on both the mass and velocity of an object, changes in momentum require an external force. Without any external force acting on the system, the total momentum remains constant, resulting in zero change in momentum.
Can a body have kinetic energy without having momentum?
Momentum = (mass) x (speed) Kinetic Energy = 1/2 (mass) x (speed)2 It looks like the only way a body can have zero momentum is to have either zero mass or else zero speed, and if either of those is zero, then that makes the KE also zero as well, too. So the answer to the question is apparently: no.
What happens to the momentum when mass is slowly decreasing but the velocity keeps constant?
Momentum = mass x velocity. Here velocity is constant. So momentum is directly proportional to the mass. Hence as mass decreases momentum too decreases proportionaly. If mass is reduced to half of its original then momentum also gets reduced to half of its original
In order to increase momentum we must increase either the object's?
mass or its velocity. Increasing the mass will increase momentum since momentum is directly proportional to mass, while increasing the velocity will also increase momentum since momentum is directly proportional to velocity.
What happens to the momentum if the mass of the object increases?
If the mass of an object increases, its momentum also increases. Momentum is directly proportional to mass, so an increase in mass will result in a proportional increase in momentum, given that the velocity remains constant.
How does the wind push against things?
Wind too is nothing but matter. So minute molecules with their movements has gained momentum and with that it could push any other matter.
What is a property of matter that is always the same no matter what size the sample?
One example of a property that remains constant regardless of sample size is density. Density is the mass of a substance per unit volume, and it stays the same no matter how much of the substance is present.
If you increase the velocity of an object the momentum of that object will?
The momentum is expressed as: p = mv, so assuming the velocity increases, the momentum of the body will increase too.
What is the physical property of matter used to determine if an objects fit on a bookshelf?
The physical property of matter used to determine if an object fits on a bookshelf is typically its size or dimensions. Objects that are too large or too wide may not fit properly on a bookshelf, while objects that are smaller in size are more likely to fit.

Are gifts your property?
if you have already given it too them, then it is no longer your property, but if you have not given it too them, them it is still yours.

Are there time limits on playing loud music on private property?
Most towns and cities have a noise ordinance, and in any situation if the music can be heard off the property it is too loud. Here in Vegas if the music or noise can be heard 70 feet away from it's source it is too loud no matter what time it is.

Can you be too old to drive a car?
Age doesn't really matter, it's just that some old age related ailments that some get impair their ability.
What happens when bending becomes too much?
when to much bending occurs and the limit is reached the rock suddenly snap or brake
