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.Know More
In physics, periodic motion pertains to cyclical movement that repeats within a regular interval. When an inert object is disturbed, it tends to move in one direction or another, causing vibrations or oscillations. A type of periodic motion called simple harmonic motion is movement that experiences a restoring force that tends to return a moving object to its equilibrium state. When a spring is compressed or stretched, the restoring force is directly proportional to how far it was displaced. This phenomena obeys Hooke's law, which states that displacement increments or decrements with respect to the restoring force. An increase in displacement also increases the restoring force while a decrease in displacement also decreases the restoring force.
Simple harmonic motion is characterized by its amplitude, frequency and period. Amplitude refers to the farthest distance the object has traveled away from its equilibrium state. Frequency relates to the number of cycles the motion undergo in one second and the time interval between two cycles is known as the motion's period. The principle of simple harmonic motion is often used in making musical instruments.Learn more about Motion & Mechanics
Water turbines convert the motion of moving water into rotating mechanical energy by catching the water with large blades. They are important to the structure and function of hydropower plants. There are different models of water turbines, but all perform the same basic function of converting the energy of the moving water into the revolutions of a shaft.Full Answer >
Force is any influence to an object which changes its motion, while motion itself is the change in position of an object in relation to is speed, location and acceleration. There cannot be movement without force used against an object to set it in motion.Full Answer >
The law of inertia is a fundamental physics principle used to describe how an object behaves in motion or at rest, particularly when forces are applied to it. The object can be anything that has mass.Full Answer >
A ball rolls because some force, such as gravity, the wind or a person's foot, acts upon it, setting it into motion. It continues to roll until some other force, such as friction, gravity or a barricade of some sort, causes it to stop.Full Answer >
