The internal energy of a system is
Kinetic energy only
Kinetic as well as potential energy
Unpredictable
Potential energy only
The internal energy of a system is the sum of all the energies i.e mechanical, chemical, potential, kinetic etc present in the system.
Can potential energy change into kinetic energy only? (directly )
Question 9 A body is falling from a height h, after it has fallen a height h2, it will possess (a) only potential energy (b) only kinetic energy (c) half potential and half kinetic energy (d) more kinetic and less potential energy
