is equal to the work done by the forces acting on the particle. These forces can either be conservative or non conservative. The force F(t) is the resultant of these forces. If gravity is acting on the particle, the work done by gravity is given by Where: ...
The work done by gravity in dropping a mass from a certain height equals the product of the weight force and the vertical displacement of the drop. The work done is also the loss in the gravitational potential energy.Answer and Explanation: We have the following details:...
If, Wg= work done by gravityWN= work done by a normal reactionWf= work done by friction forceKf= final kinetic energyKi= initial kinetic energy Then, Wg+WN+Wf=Kf–Ki Work-done Under a Constant ForceTo derive an expression for the work done under a constant force, let us assume that...
The displacement is upward and the force (gravity) is in the downward direction. Fluid resistance to flow, viscosity, is an example of negative work. Pushing an object on a rough surface. The frictional force and the displacement are in opposite directions. Kicking a ball in motion. Negative...

I did: Work done by gravity+work done by applied force= KE(final)- KE(initial) Work done by gravity should simply be -mgh =100*5=-500J For work done by applied force we know: W=∫F⋅ds which can also be written as W=∫Fdscos(θ) since F is constant i can take that out ...
E.g work done on a ball moving upward due to gravity. How to calculate work done? If you are wondering how to find work done manually then below is the guide for you. Calculate force using the force formula or our online force calculator. Force formula is F= ma. Measure angle. ...
To calculate the work done by a porter holding a suitcase weighing 5 kg in his hand, we can follow these steps:Step 1: Understand the Concept of Work Done Work done (W) is defined as the product of the force applied (F) and the
In pumping problems, the force required to lift the water to the top of the tank is the force required to overcome gravity, so it is equal to the weight of the water. Given that the weight-density of water is 9800 N/m3, or 62.4 lb/ft3, calculating the volume of each layer gives ...
