What else can I help you with?
What are the two physical quantities that are not conserved?
Entropy and work (by non-conservative force ) are not conserved
The total momentum of a group of objects is conserved unless what?
The total momentum of a group of objects is conserved unless an external force acts on the system.
Which force acts for the revolution of the earth in its own axis?
no force, just angular momentum which is conserved.
When there is no external force acting on a body , which physical quantity is conserved?
Angular Momentum. 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.
How can machines change a force involved in work?
For example, a lever does that. Please note that while there is a physical law called "conservation of energy", there is no similar law for force. Also note that force and energy are two quite different things. There is no reason why force should be conserved. If a lever reduces the force required to lift a car, for example, it also requires the force to be applied along a longer path - so energy is conserved.
When is linear momentum conserved?
Linear momentum is conserved in a closed system when there are no external forces acting on it. This means that the total linear momentum of the system before an event is equal to the total linear momentum after the event.
When momentum can be conserved?
Momentum can be conserved when the total external force acting on a system is zero. In these cases, the total momentum of the system remains constant before and after the interaction. This principle is commonly observed in situations involving collisions, explosions, or interactions between objects.
Angular momentum about the center of the planet is conserved?
Angular momentum is conserved when there is no external torque acting on a system. For a planet, the net torque acting on it is negligible, so its angular momentum about its center will be conserved unless acted upon by an external force. This conservation principle is a consequence of the rotational symmetry of the system.
How can wind be conserved for later purposes?
it can be conserved in jars.
Is rock conserved in the same sense that energy is conserved?
Not really, no.
How are white tigers being conserved?
they are conserved in a safe place
Why arent force and energy exactly the same?
Force is the rate of exchange of momentum, while energy is something that is conserved. While they are different, they have a close relationship. Energy is what you get when you apply a force over a distance. Specifically, Energy = Work= ∫Fdx. If the force is constant then, Energy = Work = F*Δx
