How much work is done when an object is thrown upward?
When an object is thrown upward, work is done against gravity as the object moves upward. The amount of work done is equal to the force applied to lift the object multiplied by the distance it moves vertically.
An object is lifted 2 m in 5 seconds by a force of 100 N.?
The work done to lift the object is 200 J (Work = Force x Distance). The power exerted to lift the object is 40 watts (Power = Work / Time).
What energy of a book on a shelf is equal to the work done to lift the book to the shelf?
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
If you lift 1600 meters straight up how much work did you do?
To calculate the work done when lifting an object, you can use the formula: work = force × distance. The force required to lift an object is equal to its weight, which is mass × gravity. So, you would need to know the mass of the object to calculate the work done when lifting it 1600 meters.
How work done against gravitational force?
Lift any object. Grav. force is acting down, you must apply an upward force to lift the object. Work is force applied through a distance, so work is done if you lift it, but not if you hold it still.
Do you do work when you lift it from the floor to a shelf?
Yes, work is done when you lift an object from the floor to a shelf. Work is the exertion of a force over a distance, and in this case, the force is applied to overcome gravity in lifting the object to a higher position.
When you perform work on an object you increase the energy of the object.?
Generally yes, but it really depends on the specific situation. -- If the work is done to lift the object, then the object's potential energy is increased. -- If the work is done to accelerate the object, then the object's kinetic energy is increased. -- If the work is done to move the object against friction, then the energy supplied is dissipated, and the object's energy may or may not change, depending on whether or not it is somewhat heated by the dissipation.
How is work done when you lift a book?
When you lift a book, you are applying a force against gravity to increase its height. Work is done when a force is applied to move an object over a distance in the direction of the force, so lifting the book requires work to be done against gravity.
How much work is needed to lift an object that weighs 500 newtons to a height of 8 meters?
The work done to lift the object is equal to the force applied multiplied by the distance moved in the direction of the force. In this case, the work done would be 500 newtons x 8 meters = 4000 joules.
What is the greater mass of an object is the force of lift?
If the mass of an object is greater than the force of lift, the object will not be able to overcome gravity and will not be able to lift off the ground. It is important for the force of lift to be greater than or equal to the mass of the object for it to be able to achieve lift.
Why is it easier to lift an object underwater than it is to lift an object on land?
It is easier to lift an object underwater because the buoyant force exerted by the water helps support the weight of the object. On land, you have to lift the object against the force of gravity without any additional support.
What kind of energy do you create when you lift something?
When you lift something, you create mechanical energy. This is a type of kinetic energy associated with the movement of objects. The energy comes from the work done by your muscles to lift the object against the force of gravity.
