This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.

What does elastic collision mean?

In an elastic collision, both kinetic energy and momentum are conserved. This means that the total kinetic energy before the collision is equal to the total kinetic energy after the collision, and the total momentum before the collision is equal to the total momentum after the collision.


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.


What are the essential characteristics of an elastic collision?

In an elastic collision, both 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 kinetic energy after the collision. Additionally, during an elastic collision, there is no loss of energy to other forms, such as heat or sound.


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.


What happens in an elastic collision?

In an elastic collision, both 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 typically results in objects bouncing off each other without any loss of kinetic energy.

What collision has no energy loss?

An elastic collision is a type of collision in which there is no net loss in kinetic energy. In an elastic collision, both momentum and kinetic energy are conserved. This means that the total kinetic energy of the system before the collision is equal to the total kinetic energy after the collision.


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.


A collision in which the total momentum and kinetic energy remain constant?

An elastic collision is one in which both momentum and kinetic energy are conserved. In an elastic collision, the total kinetic energy before the collision is equal to the total kinetic energy after the collision. This type of collision is characterized by no energy being lost or dissipated as heat or sound.


In an inelastic collision the final total momentum is?

In an inelastic collision, the final total momentum is conserved. This means that the total momentum before the collision is equal to the total momentum after the collision, even though kinetic energy may not be conserved.


What is an elastic collision with balls?

An elastic collision between balls is one in which both kinetic energy and momentum are conserved. This means that the total kinetic energy of the system before the collision is equal to the total kinetic energy after the collision, and the total momentum remains constant. In an elastic collision, the balls do not stick together and there is no loss of kinetic energy due to factors like friction or heat.


Which two properties of the system are conserved by the collision?

In an isolated system, both momentum and kinetic energy are conserved during a collision. Momentum is conserved because the total momentum before the collision is equal to the total momentum after the collision. Kinetic energy is conserved if the collision is perfectly elastic, meaning there is no energy lost to other forms (e.g., heat or sound).


How did the elastic collision effect the total momentum and total kinetik energy in the system?

In an elastic collision, the total momentum of the system is conserved, meaning the total momentum before the collision is equal to the total momentum after the collision. However, the total kinetic energy in the system is also conserved in an elastic collision, which means it remains the same before and after the collision.
