Nuclear power plants generate energy through the process of nuclear fission. In fission, the nucleus of a heavy atom, such as uranium-235 or plutonium-239, is split into two smaller nuclei, along with a few neutrons and a large amount of ...
Geothermal energy is the heat derived from the Earth’s interior. This energy can be harnessed by tapping into underground reservoirs of hot water and steam, which can then be used to drive turbines connected to electricity generators. Common methods of ...
From the work-energy theorem: −F⋅ s = − 1/2mv² Solving for the retarding force (F): F= 21 ⋅ smv²/s This gives the magnitude of the retarding force needed to stop the object over the displacement s.
The initial kinetic energy (KEi) of the object is given by the formula: KEi = 1/2 mv² where m is the mass of the object and v is its initial velocity.
It illustrates that when force and displacement are in the same direction, positive work is done, emphasizing the direct relationship between force applied and resulting displacement.
In such situations, the work done by the force is taken as positive.
The work done is equal to the product of the force and displacement.
The baby has exerted a force in the direction of displacement of the car.
The situation involves a baby pulling a toy car parallel to the ground.
