The four main types of motion are translational, oscillatory, reciprocating and rotational motion. Some mechanisms use one type of motion for input but another type entirely for output.Continue Reading
Motion is one of the most popular topics in physics, describing everything from the tiniest movement to something as large as the rotation of the a planet.
Over the centuries, scientists have discovered numerous laws that help us understand motion and the factors that cause changes in movement. Motion is driven by force, which is what gets things moving or changes the motion. Physicists use several criteria to measure motion. The speed at which an object moves, for example, is called velocity.Learn more about Motion & Mechanics
Rotary motion, also referred to as rotational motion or circular motion, is physical motion that happens when an object rotates or spins on an axis. This type of motion is analyzed in much the same way as linear motion.Full Answer >
Inertia is the tendency for an object to remain in motion or at rest unless it is acted upon by an outside force. In the field of physics, this concept is referred to as Newton's first law of motion.Full Answer >
Vibratory motion occurs at a fixed point as an object moves back and forth. It can also be defined as an object forced to move to and fro periodically, occurring when a particle is vibrated. Oscillatory motion is related to vibratory motion.Full Answer >
Instantaneous speed is an object's rate of motion at a particular time period or moment. Recording the speed of a running cheetah exactly 13 seconds after its sprint began would be an example of instantaneous speed.Full Answer >
