# Does orbital period depend on mass?

## Does orbital period depend on mass?

The period, speed and acceleration of a satellite are only dependent upon the radius of orbit and the mass of the central body that the satellite is orbiting.

Does a planet’s mass affect its orbit?

A planet’s mass does not affect a planet’s orbit around the Sun.

What factors affect the orbital period?

The orbital period of a satellite depends on the mass of the planet being orbited and the distance of the satellite from the centre of the planet.

### How does period relate to mass?

The period will increase as the mass increases. A: Newton’s second law, F = ma or a = F/m , tells us that a larger mass will have a smaller acceleration (for the same force) so that a greater mass will simply move slower and, therefore, take a longer time to complete its motion.

Does mass affect velocity in space?

Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force.

How does the mass of the star influence the orbit of the planet?

The more massive a planet or star is, the stronger the gravitational force it exerts. It is this force that allows a planet or star to hold other objects in their orbit. This is summed up in Isaac Newton’s Universal Law of Gravitation, which is an equation for calculating the force of gravity.

#### How does the mass of a planet and its distance from the Sun affect its orbit?

That is, the acceleration of a planet in its orbit around the Sun depends upon the mass of the Sun and the inverse square of the planet’s distance from the Sun. As the planet moves further away in its orbit around the Sun, the gravitational force exerted by the Sun on the planet decreases.

What can be used to determine the orbital period of a planet?

By observing the time between transits, we know the orbital period. Kepler’s Third law can be used to determine the orbital radius of the planet if the mass of the orbiting star is known (R3=T2βMstar/Msun, the radius is in AU and the period is in earth years).

How do you find mass given orbital radius and period?

The formula π = 4πΒ²πΒ³/πΊπΒ² can be used to calculate the mass, π, of a planet or star given the orbital period, π, and orbital radius, π, of an object that is moving along a circular orbit around it.

## How does mass affect the period of oscillation?

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.

Why does mass not affect the period of a pendulum?

The mass of a pendulum’s bob does not affect the period. Newton’s second law can be used to explain this phenomenon. In F = m a, force is directly proportional to mass. As mass increases, so does the force on the pendulum, but acceleration remains the same.

Does mass affect projectile motion?

Explanation: Mass is not relevant in projectile motion. What is relevant is the initial speed and direction of the object.

### How does the mass of a spacecraft affect its orbit?

They hit the ground at exactly the same time, showing that the mass of an object had no bearing on how quickly it falls. Consequently, the mass of the ISS, or any other orbiting body has no effect on its orbit. 239 views View 4 Upvoters

Does mass affect speed of orbit at a certain distance?

The size and mass of a planet have nothing to do with their rotation speed or their orbital speed. Orbital speed is controlled solely by their mean distance from the sun. The controlling relationship is P = a^ (3/2), where P is the period in years, and a is the semi-major axis of the orbit in astronomical units.

Does the mass of a satellite affect the orbit?

Why does the mass of a satellite not affect its orbit? It does, sometimes substantially. But that requires that the mass of the satellite be similar to the mass of the planet it is orbiting. If you have two objects orbiting each other, they orbit around their mutual barycenter.

#### How do you calculate orbital period?

F = force of gravity.

• M 1,M 2 = masses of the objects involved.
• R = distance between their centers of mass (usually just their centers)
• G = a constant.
