Work and Kinetic Energy – The Work-Energy Theorem Consider an object with an initial velocity ‘u’. A force F, applied on it displaces it through ‘s’, and accelerates it, changing its velocity to ‘v’. Its equation of motion can be written as: v2 –u2 = 2as Multiplying this ...
Because the mass m and speed v are given, the kinetic energy can be calculated from its definition as given in the equation KE=12mv2KE=12mv2. Solution The kinetic energy is given by KE=12mv2KE=12mv2. Entering known values gives KE = 0.5 (30.0 kg)(0.500 m/s)2, which yields KE ...

Here the work-energy theorem can be used, because we have just calculated the net workand the initial kinetic energy,These calculations allow us to find the final kinetic energy,and thus the final speed. Solution The work-energy theorem in equation form is ...
Work, potential and kinetic energy What equation links work, force and distance? A force of 10N is applied to a box to move it 2m along the floor. What is the work done on the box? If 50J of work is done on a box using 15N of force, how far was the box moved? What equation ...

And as for finding the kinetic energy, I need to use the first equation, but apparently the units of Φ should not be in eV because that wouldn't make sense, how should I calculate KE_max then? Edit: ok I converted the hf into eV, then I got the answer 1.43 eV, which is the ...
