"Dead weight"

 

This is a picture of James performing a deadlift. The Deadlift is done by lifting a loaded barbell off the ground from a stabilized bent-over position.

On the ground the potential energy = 0 because the barbell is on the ground therefore the height is 0. As he is raising the barbell PE increases and KE decreases.

 

This photo also demonstrates power. The deadlift is a common power lift for athletes hoping to increases strength and force of explosion. Power=work/time and work=(force)(distance) therefore power= (velocity)(time). The faster James lifts the weight, the more power he is using.
