Answer:
The definition of kinetic energy in Physics
“Kinetic energy of an object is the measure of the work an object can do by the virtue of its motion.”
Kinetic energy is a scalar quantity. Kinetic energy is completely described by magnitude alone.
༺꧌EXPLANATION ꧌༻
kinetic energy:
To accelerate an object we have to apply force. To apply force, we need to do work. When work is done on an object, energy is transferred and the object moves with a new constant speed. The energy that is transferred is known as kinetic energy and it depends on the mass and speed achieved.

Potential energy :
Potential energy is energy that is stored – or conserved - in an object or substance. This stored energy is based on the position, arrangement or state of the object or substance.
You can think of it as energy that has the 'potential' to do work. When the position, arrangement or state of the object changes, the stored energy will be released.
For example, it requires energy to compress a spring – but what happens to that energy once the spring has been compressed? After all, we know that energy cannot be created or destroyed, it can only be converted from one form to another.
Well, in the case of our spring, the kinetic energy used to compress the spring has been converted to potential energy. When we release the spring, the stored potential energy will be converted back into kinetic energy.

kinetic energy
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
potential energy
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
