Object Falling from Rest. As an object falls from rest, its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits the surface. K.E. = J, which is of course equal to its initial potential energy.

The Body will have both kinetic energy and Potential energy .. It will possess kinetic energy Becoz of it's movement and will Possess potential energy Becoz it will attain rest postion whatsoever at a fixed point.. say Destination as well as origination point....

Kinetic Energy
- The kinetic energy of an object is the energy it possesses due to its motion.
- When a body is freely falling, it is in motion, and therefore it possesses kinetic energy.
- The formula for calculating kinetic energy is KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is its velocity.
- As the object falls, its velocity increases, resulting in an increase in its kinetic energy.

Potential Energy
- Potential energy is the energy possessed by an object due to its position or state.
- When a body is freely falling, it experiences a change in height and therefore a change in its potential energy.
- The potential energy of an object in free fall is gravitational potential energy.
- The formula for calculating gravitational potential energy is PE = m * g * h, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height or distance from the reference point.
- As the object falls, its height decreases, resulting in a decrease in its potential energy.

Both Kinetic Energy and Potential Energy
- During free fall, the object initially has potential energy at the highest point of its fall.
- As it falls, potential energy is converted into kinetic energy.
- The total mechanical energy, which is the sum of kinetic and potential energy, remains constant in the absence of any external forces like air resistance or friction.
- At the lowest point of its fall, the object has the maximum kinetic energy and minimum potential energy.
- Throughout the fall, the total energy of the object is conserved, with the potential energy decreasing and the kinetic energy increasing.

Conclusion
- A freely falling body possesses both kinetic energy and potential energy during its fall.
- Kinetic energy is the energy of motion, while potential energy is the energy due to its position or state.
- As the object falls, its potential energy decreases, and its kinetic energy increases.
- The total mechanical energy of the object remains constant throughout the fall.
