Why does gravity not affect simple harmonic motion?

The force imparted by gravity is just mass times gravitational acceleration. For harmonic oscillation the force actually has to change in proportion to the distance from equillibrium point. Since the force imparted by gravity does not change at all it does not have any effect on the simple harmonic motion.

Is gravity required for simple harmonic motion?

So, gravity is not essential for the simple harmonic motion.

Why does restoring force is necessary for simple harmonic motion?

For a body to execute. S. M, it should oscillate about its mean position, when the body is at mean position, it possesses kinetic energy and by virtue of it, the body moves form the mean position to extreme position. …

How does gravity affect oscillation?

For gravity, the inverse relationship shows that the stronger the gravitational acceleration, the smaller the period of oscillation. For example, the period of a pendulum on Earth would be smaller compared to a pendulum of equal length on the moon.

How does mass affect simple harmonic motion?

The more massive the system is, the longer the period. For example, a heavy person on a diving board bounces up and down more slowly than a light one. In fact, the mass m and the force constant k are the only factors that affect the period and frequency of simple harmonic motion.

What is not necessary for SHM?

inertia is not required for SHM because light is the most important case of SHM and it has no inertia. otherwise gravity, elasticity or restoring forces are all encountered in SHM systems as essentials parts contributing to the motion being harmonic.

What effect does a planet’s gravitational field g have on the period of motion is it affecting the period explain why?

How does mass affect oscillation?

Mass on a Spring A stiffer spring with a constant mass decreases the period of oscillation. Increasing the mass increases the period of oscillation. For example, a heavy car with springs in its suspension bounces more slowly when it hits a bump than a light car with identical springs.

What is harmonic motion used for in research?

Simple harmonic motion is important in research to model oscillations for example in wind turbines and vibrations in car suspensions. At the University of Birmingham, one of the research projects we have been involved in is the detection of gravitational waves at the Laser Interferometer Gravitational-Wave Observatory (LIGO).

Is simple harmonic motion a good approximation of oscillations?

Whilst simple harmonic motion is a simplification, it is still a very good approximation. Simple harmonic motion is important in research to model oscillations for example in wind turbines and vibrations in car suspensions.

What are the two most common experiments that demonstrate gravitational acceleration?

The two most common experiments that demonstrate this are: 1. Pendulum – Where a mass m attached to the end of a pendulum of length l, will oscillate with a period ( T ). Described by: T = 2π√ (l/g), where g is the gravitational acceleration.

What is Hooke’s law in physics?

Hooke’s law holds up to a maximum stress called the proportional limit. Beyond the Proportional Limit. If the stress exceeds the proportional limit, the strain is no longer proportional to the. stress. The solid will return to its original shape when the stress is removed.
