Answer:
If the mass is tripled, the kinetic energy is also tripled
Explanation:
Kinetic Energy: This is the energy possessed by a body due to motion.
The S.I unit of kinetic energy is Joules.
Mathematically it can be represented as,
Ek = 1/2mv²................ Equation 1
Where Ek = kinetic energy, m = mass, v = velocity of the body.
From the equation above,
(i) Kinetic Energy is directly proportional to mass
(ii) Kinetic energy is directly proportional to velocity squared.
When the mass is tripled,
Ek₁ = 3/2mv².................... Equation 2
Comparing equation 1 and 2,
Ek₁ = 3×Ek
Therefore if the mass is tripled, the kinetic energy is also tripled
