What is work? - Work is the transfer of energy that occurs when a force is applied to an object and the object is displaced in the direction of the force.
Work is the transfer of energy that occurs when a force is applied to an object and the object is displaced in the direction of the force.
How is work calculated? - Work is calculated by multiplying the force applied to an object by the displacement of the object in the direction of the force.
Work is calculated by multiplying the force applied to an object by the displacement of the object in the direction of the force.
What is the unit of work? - The unit of work is the joule (J).
Correct! The unit of work is the joule (J), which is equivalent to the amount of work done when a force of one newton is exerted over a distance of one meter.
What is energy? - Energy is the ability to do work or cause change. It can exist in various forms such as kinetic energy, potential energy, and thermal energy.
Energy is the ability to do work or cause change. It can exist in various forms such as kinetic energy, potential energy, and thermal energy.
What is power? - Power is the rate at which work is done or energy is transferred. It is the amount of work done or energy transferred per unit time.
Power is the rate at which work is done or energy is transferred. It is the amount of work done or energy transferred per unit time.
How is power calculated? - Power is calculated by dividing the work done or energy transferred by the time taken to do the work or transfer the energy.
Power is calculated by dividing the work done or energy transferred by the time taken to do the work or transfer the energy.
What is the unit of power? - The unit of power is the watt (W).
Correct!
What is kinetic energy? - Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass and velocity of the object.
Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass and velocity of the object.
What is potential energy? - Potential energy is the energy possessed by an object due to its position or condition. It can be gravitational potential energy, elastic potential energy, or chemical potential energy, among others.
Potential energy is the energy possessed by an object due to its position or condition. It can be gravitational potential energy, elastic potential energy, or chemical potential energy, among others.
How is energy conserved in a closed system? - In a closed system, energy is conserved, meaning it cannot be created or destroyed but only transferred from one form to another. The total energy remains constant.
In a closed system, energy is conserved, which means it cannot be created or destroyed but can only be transferred from one form to another. The total energy within the system remains constant, even as it changes between different forms such as kinetic, potential, thermal, or chemical energy.
