Mechanical energy is the top because it has two types.
These two types are:
Kinetic energy - which is the energy in motion and potential energy which is the energy in reserve.
Both energy in motion and reserve is called Joules. Joules is the International System of Measurement unit for energy, this is mainly used for scaling energy in all aspects.
For Plato, K represents the stiffness of the spring. Hope this helps!
<h3>answer</h3>
The minimum velocity required for a object to rotate in a verticle plane is v
1
=
5
gr.
So, at bottom point, T
max
=mv
1
2
/r+mg=6mg.
At top-most point velocity is v
2
=gr.
So, T
min
=mv
2
2
/r−mg=0
So T
max
−T
min
=6mg=2×g⇒m=1/3 kg
FORCES HAVE STRENGTH AND DIRECTION
