Question

explain kinetic energy and potential energy with their formula and units​

Answer 1

Explanation:

Kinetic and Potential 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.

Answer 2

• Energy stored in an object due to its position is Potential Energy.

• Energy that a moving object has due to its motion is Kinetic Energy.

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity .

               $\boxed{\sf{KE = \frac{1}{2} mv^{2}}}$

 

For the gravitational force the formula of potential energy  equals to  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.

           $\boxed{\sf{PE \ due \ to \ gravity = m g h}}$
