Potential work = gravitational potential energy = mass x gravity x height = 20 x 9.8 x 10 = 1960 J or 1.96 kJ

Work = (force) x (distance) = (10) x (4) = 40 joules
work is equal to a change in energy. in this case there is a change in potential energy. potential energy = mass x gravity x height E(p)=mgh E(p)= 3x9.8x40 E(p)=1176 J thus there is a change in potential energy of 1176 joules and since W=change E(p) Work done is 1176 J
Well, isn't that a happy little question! To calculate gravitational potential energy, you can use the equation: GPE = mgh. GPE stands for gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity (which is approximately 9.81 m/s^2 on Earth), and h is the height of the object above the reference point. Just remember to embrace your mistakes and turn them into beautiful happy accidents!
If we can neglect friction and the inefficiency of human physical effort, thenthe length of the ramp doesn't matter. In rising 5 meters, the barrel gainsm g h = (40) (9.8) (5) = 1,960 joules of potential energy,so that's the work required to lift it to that height, no matter the route ormethod selected.

When work is done on a sliding block with friction, it can either increase or decrease the block's potential energy, depending on the direction of the force applied. If the work is done against the force of friction, the potential energy of the block increases. Conversely, if the work is done in the direction of the force of friction, the potential energy of the block decreases.
The work done in lifting the concrete block can be calculated using the formula: work = force x distance. Since the force required to lift the block is equal to its weight (mg), the work done is equal to the weight of the block multiplied by the height it is lifted (W = mgh). Plugging in the values given (m = 4.8 kg, g = 9.8 m/s^2, and h = 1.7 m) will give the work required in joules.
The work done to lift the block of ice is calculated as follows: Work = force × distance = 90N × 3m = 270 Joules. The potential energy (PE) of the block of ice when lifted to a height of 3m is equal to the work done to lift it, which is 270 Joules.
Work = (force) x (distance) = (10) x (4) = 40 joules
Potential energy is the type of energy stored due to gravity and height above the ground. This energy is stored energy that has the potential to do work when an object is released from that height.
Gravitational potential energy is directly proportional to the height of an object above a reference point. As an object's height increases, its gravitational potential energy also increases because the object has the potential to do more work as it falls to a lower height due to gravity. Conversely, as the object's height decreases, its gravitational potential energy decreases.
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.
Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.Gravitational potential energy is equal to mass x gravity x height.

Potential energy is related to an object's height, specifically gravitational potential energy. This type of energy increases with an object's height above the ground and is a measure of the work that can be done by gravity as the object falls.
The work required to lift the concrete block can be calculated using the formula: Work = force x distance. First, you need to calculate the force required to lift the block, which is equal to the weight of the block multiplied by the acceleration due to gravity (9.81 m/s^2). Then, multiply the force by the distance lifted (2.2 m) to find the work done.
The work done by the student to throw the ball upwards is equal to the potential energy gained by the ball at the maximum height. The work done is given by the formula: work = force * distance. In this case, the student exerted a force to lift the ball against gravity to a height of 7.50 m, so the work done is equal to the potential energy gained by the ball, which is mgh, where m is the mass of the ball, g is the acceleration due to gravity, and h is the height.
