The sum of the kinetic and potential energies of a freely falling body is constant and equal to the total mechanical energy. This is a result of the conservation of energy principle, where the body's potential energy is converted into kinetic energy as it falls, keeping the total energy constant.

What is the kinetic energy for freely falling body at the ground level?
The kinetic energy of a freely falling body at ground level is equal to its potential energy at the starting height, assuming no air resistance or other external forces are acting on it. The kinetic energy is given by ( KE = \frac {1}{2} m v^2 ), where (m) is the mass of the object and (v) is its velocity just before hitting the ground.
The potential energy of a freely falling body decreases continuouslyWhat happens to the loss of potential energy?
The loss of potential energy is converted into kinetic energy as the body falls. This kinetic energy increases as the potential energy decreases, resulting in the total mechanical energy of the body (the sum of kinetic and potential energy) remaining constant in the absence of any external forces like air resistance.
Can kinetic energy ever be more than its potential energy?
Yes, kinetic energy can be more than potential energy. For example, in an object falling freely under gravity, the kinetic energy at the bottom of the fall can be greater than the potential energy at the top due to the object's speed.
Which properties of a ball is conserved as it falls freely in a vacuum?
The mechanical energy of the ball is conserved as it falls freely in a vacuum, meaning the sum of its potential and kinetic energy remains constant. Additionally, the total momentum of the ball is conserved during its free fall.
What happens to the potential energy of a system if the objects in the system are allowed to move freely?
If the objects in a system are allowed to move freely, the potential energy of the system will decrease as it is converted into kinetic energy of the objects in motion. As the objects move, potential energy is gradually transformed into the energy of their motion.

Is there energy in an ice cube?
Yes, there is energy in an ice cube in the form of potential energy stored in the molecular bonds between the ice molecules. When heat is applied, the energy is transferred to the ice, causing it to melt and the molecules to move more freely.
When the body falls freely towards the earth then its total energy?
When the body falls freely towards the Earth, its total energy is constant. The body's kinetic energy increases as it gains speed, while its potential energy decreases as it moves closer to the Earth's surface. The sum of the body's kinetic and potential energy remains the same throughout the fall.
When an object falls freely the kinetic energy of the object will?
increase as it falls due to the conversion of potential energy to kinetic energy.
What is freely body?
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
Where does the law of gravity operate?
Freely falling bodies
What are the factors affecting freely falling bodies?
force and gravity
What are the effects of potential energy and kinetic energy to 3 states of matter?
Potential energy refers to the stored energy of an object due to its position or configuration. In a solid, potential energy is higher due to the close proximity of particles. In a liquid, potential energy is slightly lower as particles have more freedom to move around. In a gas, potential energy is the lowest as particles are far apart. Kinetic energy refers to the energy of motion. In a solid, kinetic energy is low as particles vibrate in fixed positions. In a liquid, kinetic energy is higher as particles have more freedom to move around. In a gas, kinetic energy is the highest as particles move freely and quickly.
