“motor”
.
-an engine is a ‘machine’ designed to convert 1 form of energy into ‘mechanical energy’-
.
(‘electric motors’ convert ‘electrical energy’ into ‘mechanical motion’; ‘pneumatic motors’ use ‘compressed air’ and ‘clockwork motors’ in wind-up toys use ‘elastic energy’)
(in ‘biological systems’, ‘molecular motors’ (like ‘myosins’ in ‘muscles’), use ‘chemical energy’ to create ‘forces’ and eventually ‘motion’)
