There are many examples of linear motion in everyday life, such as when an athlete runs along a straight track. Linear motion is the most basic of all motions and is a common part of life.Continue Reading
Based on Newton's first low of motion, any object that doesn't experience a net force will constantly move in a straight line at the same velocity, which is called linear motion. For example, if a person were pushed in outer space, they would continue moving at the same speed without ever stopping or changing direction unless another force acts upon them.
Linear motion is used constantly. An example of this is a car driving along a straight road. In fact, cars constantly transition between linear and rotational motion. According to HowStuffWorks, in a car engine, the pistons move in a linear motion, which is then converted into a rotational motion by the car's crankshaft. At the same time, the rack and pinion gearset of a car will convert the rotational motion of a steering wheel into linear motion, which turns the wheels.
Even power door locks are examples of linear motion. Using the same rack and pinion gearset that is found in cars, a lock will convert the rotational motion of a motor to linear motion to move the lock.Learn more about Motion & Mechanics
Examples of reciprocating motion include a rack and pinion mechanism, a Scotch yoke mechanism and a traversing head shaper. These examples define this repetitive, up-and-down or back-and-forth linear motion.Full Answer >
Common examples of simple harmonic motion include an object attached to a spring, a swinging pendulum and loudspeakers. Simple harmonic motion refers to the swinging motion exhibited by any object in the presence of Hooke's law force and absence of frictional force.Full Answer >
Some examples of periodic motion include a bouncing basketball, a swinging tire swing, a metronome or a planet in its orbit. Periodic motion is a physics term meaning the repetition of the same motion in the same amount of time.Full Answer >
Merry-go-rounds and carousels found at amusement parks are examples of mechanisms utilizing circular motion. Curves in roads and racetracks cause automobiles and their drivers to experience it. Artificial satellites and the Moon constantly undergo circular motion in their orbits around the Earth.Full Answer >
