Correct option is A
Ans. (a)
Sol. The formula for
kinetic energy (KE) is given by:
KE = 1/2 mv² Where:
·
m is the mass of the object
·
v is the velocity of the object
Thus, the correct formula for kinetic energy is
1/2 mv².
Explanation of each option:
·
(a) 1/2 mv² –
Correct answer. This is the correct formula for the
kinetic energy of an object.
·
(b) mv – Incorrect. This is not the correct formula for kinetic energy.
·
(c) 1/4 mv² – Incorrect. This is not the correct expression for kinetic energy.
·
(d) mv² – Incorrect. This is also not the correct formula for kinetic energy.
