Why is it difficult to use the law of conservation of energy to calculate the
effects of a collision?
O
A. Energy is not conserved.
O
B. Energy is only conserved during perfectly inelastic collisions.
O
C. The kinetic energy of the objects is converted to other forms of
energy
O
D. Energy is destroyed during a collision,

C. The kinetic energy of the objects is converted to other forms of

energy

Explanation:

Energy is always conserved, meaning it is neither created nor destroyed.  Instead, it changes forms.  In an inelastic collision, some of the kinetic energy is converted to other forms of energy (heat, sound, work).  

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.
