How is the conservation of momentum and kinetic energy demonstrated in a physical system?
In a physical system, the conservation of momentum is demonstrated when the total momentum before an event is equal to the total momentum after the event, as long as no external forces are present. This means that the total momentum of the system remains constant.
Similarly, the conservation of kinetic energy is demonstrated when the total kinetic energy before an event is equal to the total kinetic energy after the event, again assuming no external forces are involved. This means that the total kinetic energy of the system remains constant.
Both principles are fundamental in understanding the behavior of physical systems and are often used to analyze and predict the outcomes of various interactions.

How is momentum and kinetic energy conserved in elastic collisions?
In elastic collisions, momentum and kinetic energy are conserved. This means that the total momentum and total kinetic energy of the system before the collision is equal to the total momentum and total kinetic energy after the collision. This conservation principle helps to explain how objects interact and move in a predictable manner during elastic collisions.
Which of the conservation law does not apply to an inelastic collision?
Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
What is it called when momentum can be transferred but the total momentum does not change?
That is called an elastic collision, where momentum is transferred between objects but the total momentum remains constant. This means that the kinetic energy is conserved during the collision.
How does a basketball use the law of conservation?
A basketball uses the law of conservation of energy when it is in motion, with kinetic energy converting into potential energy and back again during play. The conservation of momentum is also at play when two players collide, with the total momentum before and after the collision remaining constant.
How does the conservation of momentum and kinetic energy play a role in the dynamics of a collision between two objects?
In a collision between two objects, the conservation of momentum and kinetic energy are important factors that determine the outcome. Momentum is the product of an object's mass and velocity, and it is conserved before and after the collision. This means that the total momentum of the system remains constant. Kinetic energy, which is the energy of motion, is also conserved in an ideal situation where no external forces are present. The distribution of momentum and kinetic energy between the objects involved in the collision can affect the resulting motion and deformation of the objects.

What form of energy does a bicycle coasting along a flat road best demonstrate?
Conservation of momentum.
What is the momentum of marbles after collision?
The momentum of marbles after collision is the same as the total momentum before the collision, according to the principle of conservation of momentum. If no external forces act on the system of marbles during the collision, the total momentum remains constant.
What is the relationship between kinetic energy and the conservation of momentum in an inelastic collision?
In an inelastic collision, kinetic energy is not conserved because some of it is transformed into other forms of energy, such as heat or sound. However, momentum is always conserved in any type of collision, including inelastic collisions. This means that the total momentum before the collision is equal to the total momentum after the collision, even if kinetic energy is not conserved.
When kinetic energy doubled what happens to momentum?
If kinetic energy is doubled, the momentum will remain the same. Kinetic energy and momentum are related, but momentum depends on mass and velocity while kinetic energy depends on mass and velocity squared. Therefore, doubling kinetic energy will not affect momentum.
Is momentum conserved in a perfectly inelastic collision?
In any physical process, momentum will always be conserved. Momentum is given by p = m*v. There is also something called law of conservation of momentum.
When a ball rolls down a hill and gains momentum is the law of momentum conservation violated?
No it is not! The hill is moving in the opposite direction. You do not perceive the motion of the hill since it move sooo slowly... When the ball will stop with respect to the hill (for instance because of an obstacle rigidly connected to the hill) then the hill will stop too. And the potential energy of the ball will be transformed into heat and sound.
What other processes accompany this kind of collision?
Inelastic collisions typically involve the transformation of kinetic energy into other forms of energy, such as heat, sound, or deformation of the objects involved. These collisions can also result in a change in momentum if the objects stick together after the collision. Additionally, inelastic collisions often involve the conservation of momentum but not necessarily the conservation of kinetic energy.
