Work is done when in physics?
Work is done when a force is applied to an object and causes it to move in the direction of the force. Mathematically, work is calculated as the force applied multiplied by the distance over which the force is applied. Work is a scalar quantity measured in joules (J).
What is the difference between power and work in the context of physics?
In physics, power is the rate at which work is done, while work is the transfer of energy that results in a change in an object's position or motion. Power measures how quickly work is done, while work measures the amount of energy transferred.
When is the work done maximum?
Work is maximum when the force applied is in the same direction as the displacement of the object. In this case, the angle between the force and displacement vectors is 0 degrees, resulting in the highest work done. This is known as positive work.
What is power in physics can it be negative?
In physics, power is the rate at which work is done or energy is transferred. Power can be negative if work is done in the opposite direction of the force applied, leading to a decrease in energy or the transfer of energy in the opposite direction.
What does power depend on physics?
In physics, power depends on both the work done and the time taken to do that work. Mathematically, power is the rate at which work is done, or the amount of energy transferred or transformed per unit time. It is typically measured in watts.

Is there such a proverb such as 'No work is done when something remains same'?
This statement can be applied to physics, so it could be considered a 'physics proverb'... Work equals force times distance, so no matter how much force is applied, if the object does not move, no work is done.
What is power in physics can it be negative?
In physics, power is the rate at which work is done or energy is transferred. Power can be negative if work is done in the opposite direction of the force applied, leading to a decrease in energy or the transfer of energy in the opposite direction.

What is the relationship between work and energy in physics?
Work done on an object is the transfer of energy to or from that object. Energy can be defined as the capacity to do work. In physics, work and energy are interconnected concepts where work is the transfer of energy from one system to another.
Where is work done?
If you mean "work" in the way it is used in physics, the basic definition of work is force x distance. In other words, if you apply a force over a certain distance, work is done.
What is an example of positive work being done in physics?
One example of positive work being done in physics is the development of renewable energy technologies, such as solar panels and wind turbines, to address climate change and reduce reliance on fossil fuels.
How much work is done when a donkey is carrying a load on it's back?
physics - no physically - yes
What are some examples of work physics problems that involve calculating the amount of work done in various scenarios?
Some examples of work physics problems that involve calculating the amount of work done include lifting a box against gravity, pushing a car up a hill, and pulling a sled across the snow. These scenarios require calculating the work done by applying a force over a distance.
How does the concept of energy being used to do work apply in the field of physics?
In physics, the concept of energy being used to do work is fundamental. Energy is the ability to do work, and in physics, work is done when a force is applied to an object and it moves a certain distance. This relationship between energy and work is crucial in understanding various phenomena in the field of physics, such as the motion of objects, the transfer of heat, and the behavior of light.
