Energy is conserved
WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy. WebKinetic energy is even conserved in the rotational motion of an object. We know that kinetic energy is conserved in translational or linear motion, and we find out using the formula KE = 1/2mv2. Similarly, even in rotational motion, KE is conserved, and it is known as rotational kinetic energy. Here the energy changes into heat when friction ...

WebNo the question does not need to specify that whether kinetic energy or momentum is conserved. It can be mathematically proven that during an ineleastic collision (like the one that happens in your question) mechanical energy is not conserved as it is spent when another body sticks to the target and gets converted into elastic and heat energy.
