is your chance to take on “the big one”: to investigate the validity of the work-energy theorem. Theory: If an amount of work, W, is done on a system, then the kinetic energy, K, of the system changes. The change in the kinetic energy is equal to the amount of work done. Sta...
The kinetic energy at the end of the upward motion was zero but it is not zero at the end of the entire downward motion. We can use the work-energy theorem to analyse the whole motion: W(round trip)=Ek,f−Ek,i=Ek,f−0=Ek,fW(round trip)=Ek,f−Ek,i=Ek,f−0=Ek,...
Learn to define work and energy. Discover the work energy theorem and the work energy theorem equation. See the relationship between work and...
W tot = ΔKE Which is called the Work Kinetic Energy Theorem Making sense? Let’s put the Work Kinetic Energy Theorem to good use… W tot = ΔKE F d Suppose there is a forceF acting on a mass m moving with velocity v o (not shown, to the right) in deep space. Let that force...
The work-energy theorem states that the net work Wnet on a system changes its kinetic energy, Wnet=12mv2−12mv20Wnet=12mv2−12mv02 .Conceptual Questions The person in Figure 4 does work on the lawn mower. Under what conditions would the mower gain energy? Under what conditions would ...
