How much work is done when you lift 100 kg of mass by 1 m?
Detailed Solution. The correct answer is 8000 J.
What is the energy of 1kg?
This implies, for instance, that 1 kilogram of matter is equivalent to an energy E = (1 kg)×(3×108 m/sec)2 = 9×1016 kg m2/sec2. An energy of 1 kg m2/sec2 is known as 1 joule, for short.
How much potential energy does a 1.0 kg object have if you raise it 1.0 m?
9.8 joulesA 1.0 kg mass lifted 1.0 meter gains 9.8 joules of gravitational potential energy.
How much thrust do you need to lift 1 kg?
10 N force is required for lifting the mass of 1 kg or 10 N force is required for lifting a mass of 1000 g.
How much force is 1kg?
That is, it is the weight of a kilogram under standard gravity. Therefore, one kilogram-force is by definition equal to 9.80665 N.
How strong is 1kW?
1,000 wattsA kWh equals the amount of energy you would use by keeping a 1,000 watt appliance running for one hour. In metric, 1,000 = kilo, so 1,000 watts equals a kilowatt. For instance, if you turned on a 100 watt bulb, it would take 10 hours to use one kilowatt-hour of energy.
What is the energy needed to raise 1kg of a substance by 1 degree?
The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
How do I calculate potential energy?
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
What is the kinetic energy of a body of mass 1 kg?
Here, mass of the body m=1 kg. Therefore, kinetic energy of the body is 2 J.
How many kg can 1 HP lift?
One mechanical horsepower lifts 550 pounds (250 kg) by 1 foot in 1 second.
Who can lift 100 kg?
Bodybuilder Nathaniel Massiah is the first of the group to make it all the way to the end and triumphantly lift 100 kgs, to rapturous applause.
How much force does it take to lift 10 kg?
The gravitational force exerted on the item is defined as a vector quantity in several mainstream textbooks. Others define weight as a scalar quantity, the gravitational force's magnitude. So, the final answer is 98 Newton.

What is the formula of 1kg?
The formula for Converting Grams to Kilograms Kg = gm/1000.
What is 1kg in physics?
It is defined as the mass of a particular international prototype made of platinum-iridium and kept at the International Bureau of Weights and Measures. It was originally defined as the mass of one liter (10-3 cubic meter) of pure water. At the Earth's surface, a mass of 1 kg weighs approximately 2.20 pounds (lb).
What exactly is 1 kg?
kilogram (kg), basic unit of mass in the metric system. A kilogram is very nearly equal (it was originally intended to be exactly equal) to the mass of 1,000 cubic cm of water. The pound is defined as equal to 0.45359237 kg, exactly.
How many joules to lift 1 kg 1 meter? - Answers
How much hydrogen is enough to lift up 1 kg weight from the ground? The weight of standard air is 1.2256 Kg/ Cubic Meter The weight of hydrogen is 0.0857 Kg/ Cubic Meter The weight of helium is 0.1691 Kg/ Cubic Meter Subtracting the weight of hydrogen from air gives you the gross buoyant lift of hydrogen as 1.1399 Kg/Cubic Meter Subtracting the weight of helium from air gives you the gross ...
power required to lift a mass - Electric motors & generators ...
One other thing, the drum shaft hp will only match the motor nameplate hp if the shaft speed matches the base speed of the motor. Otherwise, you will need a gearbox or equivalent or, if on a VFD and direct drive, the motor hp will be the constant speed torque times the motor base speed.

How much energy is needed to lift an object of mass 1kg to the height 1 m?
Therefore the energy required to lift the object of mass 1kg to the height 1 m is 9.8 Jules.
How much force does it take to lift a 1kg mass?
So to lift this 1kg mass will take more than 9.8 N. 10 newtons of life would create a net force of 0.2 N so 0.2/1 = 0.2 meters acceleration.
How many Newtons are in a watt second?
A watt-second is a joule which is also a newton-meter. Now you have to translate this from quaint, silly US units. 1 pound is 0.45 kg which exerts a force of 9.8*0.45 newtons (on earth). A foot is 0.305 metres. To get to newton-meters, multiply: 9.8 * 0.45 * 0.305 = 1.345 newton-metres, joules or watt-seconds.
How to calculate the energy required to lift a weight?
Let x kg be the mass to be lifted. The energy required = mgh
How much J do you need to lift 1 kg?
So we require 20 J to lift the body of 1 kg by 1m.
What is the potential energy required to lift an object?
The potential energy or energy required to lift the object E=mgh.
How much does a kg weigh on Mars?
On Mars, the gravity is 3.711 m/s² so a kg weighs 3.711 newtons on Mars. On Pluto, the gravity is 0.62 m/s² so a kg weighs 0.62 newtons there. I hope that explains it to you. I’ll gladly explain things to people on Quora, but I’m not going to do your homework for you.
