What else can I help you with?
What happens to the kinetic energy of an object that falls at terminal speed?
At terminal speed, the object stops accelerating due to air resistance equaling gravitational force. The kinetic energy remains constant because the object is moving at a constant speed.
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.
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.
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 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.
How is energy in potential and kinetic conserved?
For any object, the summation of its potential and kinetic energies is constant.
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 happens to an object's potential energy as it gains kinetic energy?
As an object gains kinetic energy (movement), its potential energy decreases. This is because the energy is being converted from potential energy to kinetic energy. The total mechanical energy of the object (kinetic energy + potential energy) remains constant if no external forces are acting on the object.
What is the sum of kinetic energy and potential energies?
Mechanical Energy

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.

Overall, the total energy of the system (ball and Earth) remains constant, demonstrating the conservation of energy.
What claim can you make about the relationship between kinetic energy and potential energy?
The relationship between kinetic energy and potential energy is that they are both forms of energy that can be converted into each other. Kinetic energy is the energy of motion, while potential energy is stored energy that can be released to become kinetic energy. The total energy of a system remains constant, with potential energy converting to kinetic energy and vice versa.
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.
How are potential energy, kinetic energy, and total energy related in a system?
In a system, potential energy is the stored energy that can be converted into kinetic energy, which is the energy of motion. Total energy is the sum of potential and kinetic energy in the system, and it remains constant as energy is transferred between the two forms.
