Q
As a 7kg bowling ball is raised above Dan’s foot, which two statements are true?
potential energy decreases
the amount of work being done increases
the potential energy increases
the amount of work being done decreases
Which two statements about a 7kg bowling ball relative to Dan’s foot are true?
Potential energy is maximum when the ball is at the highest point above Dan’s foot.
Once the ball is at the highest point and is held in place, the work being done is a maximum.
Before the ball is lifted above Dan’s foot, the potential energy is a maximum.
The amount of work being done increases as the ball is lifted higher and higher.
