what is the introduction of linear motion?even short its ok...thanks?

Answer 1

When a body moves in a straight line, it is said to be in linear motion.
This is the precised definition 4 linear motin.

Answer 2

Linear motors are electric motors that produce motion in a straight line rather than rotational motion.In a traditional electric motor, the rotor (rotating part) spins inside the stator (static part); in a linear motor, the equivalent components move past one another in a straight line.Linear motors often use superconducting magnets, which are cooled to low temperatures to reduce power consumption.
