How much KE is in the barbell at the start, middle, and end of the up phase?
Start/end=0
Middle= (+)
How would you expect the barbell’s kinetic energy to change when the exercise is performed faster/slower?
Yes change
Faster- more KE
Slower- less KE
How would you expect the barbell’s kinetic energy to change when the exercise is performed with longer or shorter forearms?
Yes change
Longer- increasing KE
Shorter- decreasing KE
How would you expect the barbell’s kinetic energy to change when the exercise is performed with a heavier or lighter barbell mass?
Yes change
More mass- increases KE
Less mass- decreases KE
How much gravitational potential energy is in the barbell at the start, middle, and end of the up phase?
Start- 0
Middle- (+)
End- (+)
How would you expect the barbell’s gravitational potential energy to change when the exercise is performed faster/slower?
No change
How would you expect the barbell’s gravitational potential energy to change when the exercise is performed with longer or shorter forearms?
Yes change
Faster- more PE
Slower- less PE
How would you expect the barbell’s gravitational potential energy to change when the exercise is performed with a heavier or lighter barbell mass?
Yes change
More mass- increased PE
Less mass- decreased PE
