The Hebrew term for worship is often "Avodah," which originally referred to the sacrifices offered in the Temple in Jerusalem. Today, in the absence of the Temple, it generally refers to prayer and the performance of commandments. There's also "Shachah" which literally means to bow down, usually referred to as a physical act of worship. It's always best to consult with a knowledgeable person or reliable resources if you want to understand the depth of Hebrew language and words related to religious practices.
