Question

what is kinetic energy, diffusion ,and density. Please explain ​

Answer 1

Explanation:

Kinetic Energy : It is the energy possessed by an object in motion.

$its \: formula \: is \: \frac{m {v }^{2} }{2} \: or \: \frac{ {k}^{2} }{2m}$

its SI unit is Joules (J)

Diffusion : It is the movement of matter from its higher concentration to its lower concentration.

Density : It is the amount of mass by volume of the object

Density = m(in kg)/v(in cm^3)

its SI unit is kg/m^3

THANK U !!

Answer 2

Answer:

Kinetic energy :- Kinetic energy is the energy associated with the movement of objects.The kinetic energy of an object depends on both its mass and velocity, with its velocity playing a much greater role. Examples of Kinetic Energy: 1. An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.
