They are the same- weight x distance equals weight times distance.
If the distance from the handle to the pivot (fulcrum) is n times the distance from the load to the pivot, then the force required to move the load will be the weight of the load divided by n,
d1 times w1 = d2 times w2 (d- distance of the person from seesaw)/ (w = weight of person)
The force of gravity decreases with the square of the distance from the center of the Earth. If you were five times farther from the center, your weight would be 1/25th of what it is now, and if you were ten times farther, your weight would be 1/100th of your current weight. Therefore, you'd weigh significantly less the farther you are from the Earth's center, illustrating the inverse square law of gravitation.
If you moved 3 times further from the center of the Earth, your weight would decrease by a factor of 9. This is due to the inverse square law of gravity, which states that gravitational force decreases with the square of the distance.
Force times distance equals work.
Lifting a 50 newton weight 3 meters straight upward requires more work than lifting a 30 newton weight the same distance. Work is calculated using the formula ( \text{Work} = \text{Force} \times \text{Distance} ). For the 50 newton weight, the work done is ( 50 , \text{N} \times 3 , \text{m} = 150 , \text{J} ), while for the 30 newton weight, it is ( 30 , \text{N} \times 3 , \text{m} = 90 , \text{J} ). Thus, lifting the 50 newton weight involves more work.
Force times Distance equals Work
Mechanical energy and work are the same thing. Work is the force times the distance moved in the direction of the force. So lifting a 1 kg mass by 1 metre represents an amount of work equal to the weight times the distance: 9.806 Newtons times 1 metre equals 9.806 Joules.
weight = gravity times massand weight = density times volume
d=rt distance= rate[times] distance= rate * times
Force times distance is called "Work" for the purposes of physics.
