An elastic collision is a type of collision between two objects where kinetic energy is conserved. This means that the total kinetic energy of the two objects before the collision is equal to the total kinetic energy after the collision.
The velocities of two objects after an elastic collision can be calculated using the principles of conservation of momentum and conservation of kinetic energy. This involves setting up equations using the mass, initial velocities, and final velocities of the two objects and solving for the unknowns.
An elastic collision is a type of collision where kinetic energy is conserved, while an inelastic collision is a type of collision where kinetic energy is not conserved. In an inelastic collision, some of the kinetic energy is converted into other forms of energy, such as heat or sound.
Yes, elastic collisions can occur in real life. For example, when two billiard balls collide on a pool table, the collision is close to being elastic. In reality, there may be some loss of kinetic energy due to friction, but the collision is still considered elastic.
Elastic collisions have many real-life applications, including in sports such as billiards and ping pong, as well as in engineering and physics experiments. They are also used in the design of airbags for cars, where the collision between the car and an object needs to be as elastic as possible to minimize damage.
