How much potential work can a 20 KG block do at a height of 10 m?
Potential work = gravitational potential energy = mass x gravity x height = 20 x 9.8 x 10 = 1960 J or 1.96 kJ
How much work is done when lifting a 10 kg mass up a distance of 20 m?
Use the formula for potential energy: PE = mgh (mass x gravity x height). Since you are using SI units, use 9.8 for gravity.
The height of a projectile in motion is dependent on what?
Projectile motion is a form of motion wherein an object moves along a curved path under the action of gravity only. The height of a projectile in motion is dependent on gravity.
What factors affect the amount of gravitational potential energy?
Mass, gravity, height.
Which requires more work lifting a 25 kgbag of cement 10 meters vertically or lifting a 50 kgbag 5 meters vertically?
I think the formula is something like work (energy) is mass by height by gravity. as gravity is a constant, dont worry about it in comparison. 25*10 is 250 50*5 is 250. They require the same effort
How much work is done by gravity as the riders are lifted to a height of 60 meters?
Gravity does not lift. The force is doing the work by lifting the riders. When the riders come down from the 60 meter height, then gravity will be at work.
How do I work out a vertical height when it gives me kg and kJ of Ep and Gravity?
Ep (joules) = mass * acceleration due to gravity * height So: height = Ep / (mass * acceleration due to gravity)
When you throw a substance in air at what height there in no gravity at what height there is least gravity and at what height there is normal gravity?
The farther it is from Earth, the less gravity will there be. Gravity will never completely disappear.
How does gravity affect a person's height or stature?
Does gravity affect a person's height and why?
What type of energy stored due to gravity and height above the ground?
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.
What factors affect the ability of gravity to do work?
The factors that affect the ability of gravity to do work include the distance the object falls, the mass of the object, and the presence of other forces that may oppose gravity, such as friction or air resistance. The work done by gravity is determined by the height through which the object falls and the force of gravity acting on the object.
When is work said to be done against the force of gravity?
Work is said to be done against the force of gravity when an object is moved vertically upwards, against the force of gravity, over a certain distance. In this case, the force applied must be greater than the force of gravity acting on the object for work to be done against gravity.
does gravity increases or decreases with height?
It decreases with height.
How much work has done to lift a 1000 kg block?
The work done to lift a 1000 kg block depends on the height it is lifted to and the force applied. Work done is calculated as force x distance. The formula is Work = force x distance x cos(theta), where theta is the angle between the force vector and the displacement vector.
How do you calculate the work done if a boy lifts a body of 50kg to a height of 20m?
work done = m*g*h = mass * acceleration due to gravity * height change. work done = 50 * 9.8 * 20 work done = 9 800 joules
A student throws the same ball straight upwards to a height of 7.50 m how much work did the student do?
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.
How can the gravitational potential energy of an object be changed?
The gravitational potential energy of an object can be changed by altering its height or distance from the Earth's surface. Moving the object to a higher position increases its potential energy, while moving it closer to the surface decreases its potential energy. Additionally, changes in mass can also impact the gravitational potential energy of an object.
