Energy & Work
Apply a force to move an object. Notice how the energy you put in (work) changes its speed.
Work done on an object increases its kinetic energy. This is the foundation for understanding energy transfer.
If you double the force or distance, how does the energy change? Try different values.
W = F imes d = Delta KE = rac{1}{2}mv^2 - rac{1}{2}mu^2
Use this formula to calculate the relationship between different variables in this concept.
If you push a 2 kg block with 10 N over 5 m, the work done is 50 J. This increases the block's kinetic energy by 50 J.
