What is the work done against gravitational force if an object of 20 kg mass is raised to a height of 2m?
W = mgh = 20 × 9.8 × 2 = 392 J.
How much force do we required to lift an object of 1kg?
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. Note that, gravitational force is one side of the same coin, with acceleration on the other.
How much work will be done to lift 20kg weight on a height of 20m?
The work done is the product of force and displacement. Force is the product of mass and acceleration which in this case is acceleration due to gravity. Thus the work done to lift the load is 196J.
How much work is done to lift a 20kg sack of potatoes vertically 6.5 m use 10ms 2?
How much work is it to lift a 20. kg sack of potatoes vertically 6.5 m? E = mg = 2oka x 9.806² = 10 UN W=Fd 1960 x 65m = 112745.
How much work does it take to lift 1kg up 1 meter?
Lifting Weights: On earth it takes about 10 Newton-meters (N-m) of energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s 10 Joules. If it takes 1 second to lift the weight 1 meter, than you have converted 10 Joules of energy to potential energy in one second.
How much force does it take to move a 20kg object?
Using a ramp of length 2m, you apply a 150N force to move a 20kg object a vertical distance of 1m. How much work does gravity do on the object? How much work (energy) is needed to lift an object that weighs 200N to a height of 4m?
How do you calculate the force required to lift a 5kg?
Calculate the force required to lift the 5-kg mass 10 m. W = F × ∆d; where W is work, F is force, and ∆d is displacement. The unit for work is kg•m²/s², which is a Newton-meter, or N•m, and is called the Joule (J).
What is the work done if the object is 10m tall?
The work done would be the change in kinetic energy as the object moved 10 m. Work done = change in KE = 1 / 2 ∗ m ( 10000 / m 2 − 0) = 5000 / m Joules. The work done in this case will depend on the mass of the object. If 5kg mass is lifted on 10m height, how much work will be done?
What is the energy required to lift the box half a meter?
Because gravity applies a force of -343N, to lift the box one must apply a force of +343N. In order to find the energy required to lift the box half a meter, we must multiply this force by half a meter.
