If the speed of an object is tripled, its kinetic energy will be 9 times the initial value.
What is kinetic energy?
The kinetic energy of an object is the energy possessed by the object due to its motion.
K.E = ¹/₂mv²
where;
m is mass of the object
v is speed of the object
When the speed is tripled
K.E = ¹/₂m(3v)²
K.E = 9(¹/₂mv²)
Thus, if the speed of an object is tripled, its kinetic energy will be 9 times the initial value.
