What does the kinetic energy of an object increase with?

Solution:

The energy which an object has gained because of its motion is called it is kinetic energy.
The kinetic energy of an object is given as:
K.E. = $1/2$ m × $v^2$ where,
m = mass of object, v= Velocity of Object
Hence, Kinetic Energy (K.E.) is directly proportional to the square of the velocity.
Hence, by increasing the speed of the object K.E. also increases.
