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.
Can photons collide with each other?
Yes, photons can interact with each other through a process called photon-photon scattering, where they can exchange energy and momentum.
What is the relationship between energy, as measured in joules, and momentum, as measured in kgm/s?
The relationship between energy (measured in joules) and momentum (measured in kgm/s) is that they are both important physical quantities in the study of motion. Energy can be transferred between objects to change their momentum, and momentum can be used to calculate the amount of energy involved in a collision or interaction. In simple terms, energy and momentum are related in the context of how objects move and interact with each other.
What is necessary condition for the conservation of momentum?
No external forces. Objects may bounce off each other, or merge but the total momentum is unchanged even when the total energy changes.
What is elastic and inelastic collisions in terms of momentum?
In elastic collisions, both momentum and kinetic energy are conserved. This means that momentum before and after the collision is the same, and the objects bounce off each other without any loss of kinetic energy. In inelastic collisions, momentum is conserved but kinetic energy is not. Some kinetic energy is converted into other forms of energy, such as heat or sound, during the collision.
When a particle and an antiparticle come in contact with each other then what happend?
When a particle and an antiparticle come in contact with each other, they annihilate each other and their mass is converted into energy, typically in the form of photons (light). This process is governed by the laws of conservation of energy and conservation of momentum.
Can momenta cancel?
Yes, momenta can cancel each other out if they have equal magnitude but opposite direction. When two objects collide and the total momentum before the collision is equal to the total momentum after the collision, the individual momenta can cancel each other.
Can 2 interacting objects have momentum but no kinetic energy?
no kinetic energy is basically "in motion", momentum is built upon speed, weight, and strength of a moving object. if you would like the definition of potential energy it is the ability or placement of an object before kinetic energy forms
What is the difference between momentum and kinetic energy, and how do they relate to each other in the context of physics?
Momentum is the mass of an object multiplied by its velocity, while kinetic energy is the energy an object possesses due to its motion. Momentum is a vector quantity, meaning it has both magnitude and direction, while kinetic energy is a scalar quantity, only having magnitude. In the context of physics, momentum is related to the amount of motion an object has, while kinetic energy is related to the work needed to accelerate an object to its current speed. The two are related in that an object's kinetic energy is directly proportional to its momentum.
What type is it when 2 objects bounce off each other when they collide and may transfer what from one to the other?
It is the second type of collision. And they may transfer momentum from one to the other.
What are the metal balls that knock against each other called?
Those are called Newton's cradle. It is a device that demonstrates conservation of momentum and energy.
How are the movements of energy and nutrients different from each other?
they crazy.
