Answer:
Work done during lifting up body is 0
Explanation:
From the question it is given that
Distance traveled by body during lifting is 2 m
since work done by body is given by
work done W = F x s x cosθ
Where F= mg = weight of body
s= distance traveled = 2m
θ = angle between force and distance vector
here θ = 90° as body is lifting up
on substituting the respected values we get
⇒ W = mg x 2 x cos90° = 0 {∵ cos90°= 0 }
Thus, work done during lifting up body is 0
Answer:
It has gravitational potential energy because of its height.
Its atoms and molecules have thermal energy.

I'm a bit late, but here's an answer
The motion of a car and the wheel is kinda interesting, actually. If the wheel is turned right, the wheels will turn right. If it's left, the wheels will go left, you get the idea. The car will move that direction if it's in motion, though.
