Which requires more work-lifting a 50 kgsack a vertical distance of two meters or lifting a 25kg sack a vertical distance of four meters?
They require the same amount of work because the formula for work is force times distance.
How can the same amount of work be done if the forces acting on the object are different?
It depends on the distance over which the work is done. Work = Force x distance
How much work is done when a 700 N refrigerator is lifted straight up a distance of 4 meters in joules?
Work is done in lifting is equal to work done in opposing gravity. Work done in opposing gravity = weight times distance = 700 x 4 =2800 joules
The amount of work done on an object is obtained by multiplying?
Force • distance
What type of work is being done when pulling?
The same type as is done when pushing, shoving, rolling, lifting, wiggling etc. ... a force acting through a distance.

What are the two ways in which you can increase the amount of work done?
By increasing the distance also increasing the amount of work done
How can the same amount of work be done if the forces acting on the object are different?
It depends on the distance over which the work is done. Work = Force x distance
How do you find the amount of work done on an object?
Work = force x distance.

Work is done in lifting is equal to work done in opposing gravity. Work done in opposing gravity = weight times distance = 700 x 4 =2800 joules

What are the factors that affect the amount of work done?
There are two factors on which work done depends. 1:- Force2:- Distance or displacement

The same type as is done when pushing, shoving, rolling, lifting, wiggling etc. ... a force acting through a distance.
Why does a ramp not reduce the amount of work. Please explain in words or with numbers?
Assuming 100% efficiency, the amount of work depends on the weight and the vertical distance (that is, opposite to the pull of gravity) moved. If you use a ramp then you reduce the force by an amount k, that's true, but the distance you have to push in the direction of the force is multiplied by k. The work done is [original force]/k times [vertical distance]times k and the k cancels out. For vertical lifting k=1.
What is the distance when you exerted 100N and amount of work done is 600J?
6 m
What is the formula for work given force distance and time?
Work = (force) x (distance). Time is not involved.But if that amount of work was done in that amount of time, then(force) x (distance)/(time) is the average power during that time.
Do pulleys make you work less?
No. If you are, say, lifting a weight the amount of work done is the same whether you use a pulley or not. However, you may not be able to actually lift the weight unless you use a pulley. But the amount of work done will be the same with or without the pulley.
