Answer 1

Explanation:

define kinitic energy :

$\huge{\underline{\blue{\mathfrak{♡Answer♡}}}}$

⠀⠀⠀⠀⠀⠀Kinetic energy is energy possessed by an object in motion. The earth revolving around the sun, you walking down the street, and molecules moving in space all have kinetic energy.

FORMULA :

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2.

Potential Energy :

$\huge{\underline{\red{\mathfrak{♡Answer♡}}}}$

⠀⠀⠀⠀⠀⠀Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.

FORMULA :

⠀⠀⠀⠀⠀⠀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.

Mechanical Energy :

$\huge{\underline{\blue{\mathfrak{♡Answer♡}}}}$

⠀⠀⠀⠀⠀⠀Mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant.

FORMULA :

⠀⠀⠀⠀⠀⠀The formula for mechanical energy is mechanical energy = kinetic energy + potential energy.
