👉 The term "constrained" or "constraining" is used in mathematics, physics, and other fields to describe an object that cannot move freely. It refers to a set of constraints on its motion such as mass, velocity, acceleration, etc., which must be satisfied for the object to remain at rest or moving at constant speed. For example, consider a car that needs to maintain a certain speed for safety while traveling. If the car is constrained by an obstacle like a wall or a
