Elastic collision is a type of collision where kinetic energy and momentum are conserved.

• In an elastic collision, the total kinetic energy of the system before and after the collision remains the same.

• Both momentum and kinetic energy are conserved in elastic collisions.

• Objects bounce off each other without any loss of energy in an elastic collision.

• Examples of elastic collisions include billiard balls colliding on a ta...read more

The second law of motion states that the force acting on an object is directly proportional to its mass and acceleration.

• Force = mass x acceleration

• The greater the force applied, the greater the acceleration produced

• The greater the mass of an object, the greater the force needed to accelerate it

• Examples: pushing a heavy box requires more force than pushing a light box; a car requires more force to accelerate than a bic

Degree of freedom refers to the number of ways a molecule can move in space. A diatomic molecule has 5 degrees of freedom.

• Degree of freedom is the number of independent ways a molecule can move in space

• For a diatomic molecule, there are 5 degrees of freedom: 3 translational and 2 rotational

• Translational degrees of freedom refer to movement in x, y, and z directions

• Rotational degrees of freedom refer to rotation about t...read more

The expression for the energy of a hydrogen atom is -13.6 eV/n^2.

• The energy of a hydrogen atom is determined by the equation E = -13.6 eV/n^2

• The energy levels of hydrogen are quantized and can be calculated using the Rydberg formula

• The energy of a hydrogen atom can be calculated using the Bohr model

• The energy of a hydrogen atom is related to the ionization energy required to remove an electron

• The energy of a hydrogen a

Box potential refers to the maximum potential energy that can be stored in a confined space.

• Box potential is a concept in physics that is used to describe the maximum amount of energy that can be stored in a confined space.

• It is often used in the context of particle physics and quantum mechanics.

• The box potential is determined by the size and shape of the container, as well as the properties of the particles or waves t...read more
