Mechanical energy is the type of energy that is present in a barbell being lifted or a shot put being thrown.
Mechanical energy is the type of energy that is present in a barbell being lifted or a shot put being thrown.
The potential energy increases because of the weightlifter lifting it above his head (Hope this helps)XP
Work = Force x distance So since the barbell is 500N and the barbell travels 2.2 meters it becomes 500N x 2.2m = 1100 joules (N x m)
The same amount of potential energy again.
Double the first potential energy.

kinetic energy being enacted. this energy is giving rise to potential energy too, as the item is being lifted into the air. When an item is lifted, it is given potential energy, as this potential energy is what fuels its future descent. So, when moved, kinetic energy is both moving the object, and storing potential energy for future use.
The power during the lift is (weight of the barbell in Newtons)/4.4 watts.Note:Power is not "expended". Energy is. Power is the rate at which energy is expended.

The present perfect tense of lift is:I/You/We/They have lifted.He/She/It has lifted.
