What type of motion is planetary motion?

Earth rotates on its own axis and this type of motion is called rotation. Earth also rotates around the sun in an elliptical orbit and such motion is called a revolution. Earth rotates on its own axis and this type of motionis called rotation.

What qualifies as simple harmonic motion?

simple harmonic motion, in physics, repetitive movement back and forth through an equilibrium, or central, position, so that the maximum displacement on one side of this position is equal to the maximum displacement on the other side. The time interval of each complete vibration is the same.

Which motion is not SHM?

The motion of a planet around the sun is a periodic motion but not a simple harmonic motion. All other given motions are the examples of simple harmonic motion.

What is meant by planetary motion?

Three laws devised by Johannes Kepler to define the mechanics of planetary motion. The first law states that planets move in an elliptical orbit, with the Sun being one focus of the ellipse. This law identifies that the distance between the Sun and Earth is constantly changing as the Earth goes around its orbit.

Is pendulum simple harmonic motion?

Thus, simple pendulums are simple harmonic oscillators for small displacement angles.

Can a motion be oscillatory but not simple harmonic?

Yes, when a ball is dropped from a height on a perfectly elastic plane surface, the motino of ball is oscillatory but not simple harmonic as restoring force F=mg= constant and not F∝-y.

Why motion of planet around the sun is not simple harmonic motion?

But in case of earth there exist a centralized force that acts towards center (sun) but it is proportional to inverse of square of the displacement between earth and sun thats why motion can’t be SHM. Linear Simple harmonic motion is to and fro motion of particle along straight line.

What are the examples of non periodic motion?

Examples of non-periodic motion:

• Movement of particles in air.
• Swaying of the branches of a tree.
• Motion of tides in the ocean.
• The running of a batsman between the wickets.
• Flowing of water into the streets during floods.
• Motion of birds flying in the sky.
• Application brakes in a moving vehicle.

What are the three planetary motion?

There are actually three, Kepler’s laws that is, of planetary motion: 1) every planet’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its …

What are the 3 laws of planetary motion?

In astronomy, Kepler’s laws of planetary motion are three scientific laws describing the motion of planets around the sun. Kepler first law – The law of orbits. Kepler’s second law – The law of equal areas. Kepler’s third law – The law of periods.

What is simple pendulum in simple harmonic motion?

A pendulum in simple harmonic motion is called a simple pendulum. A pendulum has an object with a small mass, also known as the pendulum bob, which hangs from a light wire or string. The equilibrium position for a pendulum is where the angle θ is zero (that is, when the pendulum is hanging straight down).

What factors affect the period and frequency of simple harmonic motion?

The stiffer the spring is, the smaller the period T. The greater the mass of the object is, the greater the period T. The mass m and the force constant k are the only factors that affect the period and frequency of simple harmonic motion.

How does Hooke’s law apply to simple harmonic motion?

The simplest oscillations occur when the restoring force is directly proportional to displacement. Recall that Hooke’s law describes this situation with the equation F = − kx. Therefore, Hooke’s law describes and applies to the simplest case of oscillation, known as simple harmonic motion.
