Kinetic energy of an object is increasing and potential energy remains constant explain in tems of conservation of energy?
This can happen if there is an external force acting on the object. Then the object is accelerating, and its kinetic energy is increasing. The extra energy comes from the external force. Example: Push a Bowling ball on a long table. It keeps rolling faster, its kinetic energy increases, but its potential energy due to its height doesn't change, until it reaches the edge of the table and starts to fall.
What else can I help you with?
Are potential and kinetic energy equal in a closed system?
In a closed system, potential and kinetic energy can change but their total remains constant. This is known as the conservation of energy.
If a particle falls through a height its potential energy decreases. does this violate the law of conservation of energy explain why?
No, it does not violate the law of conservation of energy. When a particle falls, its potential energy is converted into kinetic energy. The total energy (potential + kinetic) remains constant, demonstrating the conservation of energy.
The sumof the kinetic and potential energies of a freely falling body is?
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.
How do kinetic and potential energy work work together?
Kinetic energy is the energy of motion, while potential energy is stored energy. In a system, potential energy can be converted into kinetic energy as an object moves and gains speed. The sum of an object's kinetic and potential energy is constant, demonstrating the principle of conservation of energy.
Does the total mechanical energy of a system remain constant, even when the kinetic energy equals the potential energy?
Yes, the total mechanical energy of a system remains constant even when the kinetic energy equals the potential energy. This is known as the conservation of mechanical energy.

What happens to kinetic energy and potential energy in a closed system?
In a closed system, the total energy (kinetic + potential) remains constant, following the principle of conservation of energy. As kinetic energy increases, potential energy decreases, and vice versa. This continuous exchange between kinetic and potential energy allows the system to maintain a constant total energy.

What energy conservation occurs when a ball rolls down a hill?
When a ball rolls down a hill, potential energy is converted into kinetic energy. As the ball moves downward, its potential energy decreases while its kinetic energy increases. This is an example of the conservation of mechanical energy, where the sum of potential and kinetic energy remains constant in the absence of external forces like friction.
How is energy conserved when you throw a ball into the air and then catch it?
When you throw a ball into the air, you are giving it kinetic energy. As the ball rises and slows down, this kinetic energy is converted into potential energy. When you catch the ball, you are transferring this potential energy back into kinetic energy. Overall, the total energy of the system (ball and Earth) remains constant, demonstrating the conservation of energy.
Why can't kinetic energy exceed potential energy?
Kinetic energy cannot exceed potential energy because the total mechanical energy of a system is conserved. When an object gains kinetic energy, it does so at the expense of potential energy, and vice versa. This conservation principle ensures that the sum of kinetic and potential energy remains constant in a closed system.
What relationship between the potential and kinetic energy as the objects rolled down the inclined plane?
As objects roll down an inclined plane, potential energy is converted into kinetic energy. As the object loses height (potential energy), it gains speed and energy of motion (kinetic energy). The sum of potential and kinetic energy remains constant, in accordance with the law of conservation of energy.
How is energy in potential and kinetic conserved?
For any object, the summation of its potential and kinetic energies is constant.
