What is kinetic energy? a. the energy an object has due to its motion b. the energy derived from chemical reactions c. the energy an object has due to its position d. the energy an object releases as heat

Option (a) is correct.

Explanation:

When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object.

The formula to calculate kinetic energy is as follows.

                   kinetic energy =

where,    

            m = mass of object

            v = velocity of object

Thus, it is concluded that kinetic energy is the energy an object has due to its motion.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
