work is force x distance; force required to move 200 kg rock is 200 x 9.8m/s/s = 1960N; 1960 x 10 = 19600 joules
It is 2 kilojoules.
2000 joules
21 truck loads. 35.7 Divided by 1.7 = 21
If an object does not move, no work is performed. Work is performed by a force acting through a distance.
A). Vertical displacement = 12.5 sin(20) = 4.275 meters (rounded)B). Horizontal displacement = 12.5 cos(20) = 11.746 meters (rounded)
If you have moved forward and backward, hence ending up at the same point you started, then displacement is zero. That's because Displacement takes into account the direction - hence a vector quantity.The distance only bothers about the distance - hence it doesn't matter if you came to where you started. So in total, 5 meters up and 5 down is 10. Distance = 10
Judge by the distance it has moved in relation to another object.

(4 x 5) kilogram-meters = 20 joules
The work is 347 joules.
Work = force x distance = Newtons x meters = 1937 Joules.
Assuming the force doesn't change, and the force and movement are in the same direction, the energy (the joules) is the product of distance and force. Thus, you just need to divide the energy by the distance.
Work Done = Force x Displacement 2.7 joules = 4.5 newtons x Displacement(in meters) Displacement = 0.6 meters
The distance moved by the object can be calculated by dividing the work done by the force applied. In this case, the distance is 15 meters.
Work= 1500 Joule. Time= 60 100 N is moved 15 meters. Work = applied force (newtons) x distance (meters) X = 100 x 15 Work = 1500 Joules Power (watts) = work (joules)/ time (seconds) 25 = 1500/X Time = 60.
Work is defined as (force) times (distance). If the force is not zero, and the distance it moved through is not zero, then work was done. In other words, if you applied a force, and kept it going while the place you applied the force moved, then work was done. In this case, work = (60) x (0.5) = 30 newton-meters = 30 joules of work.
the decimal is moved to right three times.
When an object is moved by a force, work is done, increasing or decreasing its kinetic energy, often but not always decreasing or increasing its potential energy.
A joule is defined as 1 kg being lifted 1 meter. Ergo 14 kilograms moved by 1 meter takes 14 joules.
