_____ energy = Potential energy + Kinetic energy
Answers
Mechanical energy = K.E +P.E
Answer:
Mechanical energy= Potential energy+kinetic energy
Explanation:
Kinetic energy
The energy produced by a body in motion is known as kinetic energy. Eg. a moving ball posseses kinetic energy. In which mass of the object is directly proportional to the kinetic energy and the square of velocity of the body is directly proportional to the kinetic energy.
The formula of Kinetic energy= 1/2mv^2
Where,
m=mass of the object
v=velocity of the object
Potential energy
The energy of an object which is at rest is known as potential energy. Eg. a ball which is at a height, posseses potential energy. In this type of energy, mass, gravity and height at which the object is kept are directly proportional to this energy.
The formula for potential energy= m×g×h
Where,
m=mass of the object
g=gravity at that place
h=height of the object
