This statement is not necessarily true. The internal energy of a system can increase, decrease, or remain the same depending on the type of work done on it.

Here's a step-by-step explanation:

1. Internal energy: This is the total energy stored in a system. It includes kinetic energy (due to the motion of particles) and potential energy (due to the forces between particles).

2. Mechanical work: This is the work done on a system when a force is applied to it, causing it to move.

3. Work-Energy Principle: This principle states that the work done on a system will change the system's energy. If the work is done on the system (like compressing a gas), it will increase the system's internal energy. If the work is done by the system (like a gas expanding), it will decrease the system's internal energy.

4. However, it's important to note that heat transfer can also affect a system's internal energy. If heat is added to the system, its internal energy will increase. If heat is removed from the system, its internal energy will decrease.

So, doing mechanical work on a system can increase or decrease its internal energy, depending on the specifics of the work done and whether or not there is heat transfer.
