Question

what is collision? explain different types of collision along with examples &state there characteristics?(each5)​

Answer 1

Answer:

collision is an event where momentum or kinetic energy is transferred from one object to another. ... There are two general types of collisions in physics: elastic and inelastic. An inelastic collisions occurs when two objects collide and do not bounce away from each other.

Answer 2

Answer:

Explanation:

Definition:-

A collision is the event in which two or more bodies exert forces on each other in about a relatively short time.

Types of Collisions:-

• Inelastic collision-Collision which conserves momentum but not kinetic energy.
• Elastic collision:-Collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions.

• Totally inelastic collision-Collision where the objects stick together and have the same final velocity. It is also called a perfectly inelastic collision.

Examples:-

Inelastic Collision:-

• An inelastic collision in a ballistic pendulum.

• A dropped ball of clay doesn't rebound. Instead it loses kinetic energy through deformation when it hits the ground and changes shape.

Elastic collision:-

• Collisions between atoms in gases.

• Two similar trolleys are traveling toward each other with equal speed. They collide, bouncing off each other with no loss in speed. This collision is perfectly elastic because no energy has been lost.

Characteristics of Elastic Collision:-

1. The Momentum is conserved.
2. Total energy is conserved.
3. The kinetic energy is conserved.
4. Forces involved during the collision are conservative.
5. Total kinetic energy and the total momentum before and after the collision are the same.

Characteristics of Inelastic Collision:-

1. Kinetic energy is not conserved.
2. In macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.
3. Some of the energy gets converted into other forms of energy such as sound energy or thermal energy.
4. Momentum is conserved.
5. A zero coefficient of restitution, the colliding particles stick together.
