Whats the difference between ATP and ACh?

In relating to muscle movement and contractions, whats the difference between those two?

Is it just ATP is the actual energy source while ACh is the compound that sends the signal to the muscle cells to move, which causes the ATP to activate?

Thanks!

    Although ATP is the source of energy used by all cells it can also function as a neurotransmitter

    so it sounds, from your assessment, that you understand

    ACh is the neurotransmitter for all skeletal muscles and they use ATP as their energy source
