Does elastic potential energy depend on mass?
Kinetic energy depends on an object’s mass and velocity. Potential energy is the energy stored in an object because of its position or shape. It includes gravitational potential energy and elastic potential energy. Gravitational potential energy depends on an object’s weight and height above the ground.
Is momentum conserved in a spring?
It’s important to understand that the spring and the mass on the end of it are not a closed system. Momentum is conserved because the forces acting on the two identical masses are equal and opposite, so the rate of change of momentum of the two masses is equal and opposite, and cancels out leaving zero.
Is momentum conserved when a block hits a spring?
Energy is conserved as long as you consider the spring as part of the system. But once the collision is over, A starts moving with some velocity – and then it will compress the spring, and the resulting force will transfer momentum from A to B.
How is momentum conserved when energy is lost?
What is an inelastic collision? An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. This type of collision is perfectly inelastic because the maximum possible kinetic energy has been lost.
Is momentum conserved when there is friction?
Conservation of momentum applies when net force is zero. Total momentum of the system is zero before canonball is fired. Now canonball is fired from the canon, and in frictionless cases, horizontal-axis momentum of the whole system would be preserved.
Is momentum conserved in an explosion?
Whether it is a collision or an explosion, if it occurs in an isolated system, then each object involved encounters the same impulse to cause the same momentum change. The impulse and momentum change on each object are equal in magnitude and opposite in direction. Thus, the total system momentum is conserved.
