gabriel.dac said:When the planet's r is greater... the fource would become lower compared to the planet being FARTHER from the sun.
Also, call it star, not Sun. The Sun is our star
itachipower said:What if it was a ball attached to a string? How would that be different from a binary planet-star system?
gabriel.dac said:The planet would have smaller centripetal acceleration because it would be moving slower than if it was closer to the Sun. It needs less speed to stay in orbit
itachipower said:So my teacher said that an object farther from the center experiences greater centripetal acceleration. How is that possible? let's say we have a sun + planet system. F = GmM/r^2 so when the planet's r is greater, wouldn't the force become lower compared to the planet being closer to the sun?
Angular acceleration of a planet is the rate at which the planet's angular velocity changes over time. It is a measure of how quickly the planet is rotating around an axis.
Angular acceleration of a planet can be calculated by dividing the change in the planet's angular velocity by the change in time. This can be represented by the formula: α = (ω2 - ω1) / (t2 - t1), where α is the angular acceleration, ω is the angular velocity, and t is the time.
The angular acceleration of a planet can be affected by several factors, including the planet's mass, distance from the sun, and the gravitational force exerted by other objects in its orbit. The planet's shape and rotation can also play a role in its angular acceleration.
Angular acceleration is directly related to a planet's orbit. As a planet's angular acceleration increases, its orbital speed also increases, causing it to orbit the sun at a faster rate. This means that the planet will complete its orbit in a shorter amount of time.
Yes, the angular acceleration of a planet can change over time. This can be due to external forces, such as gravitational pull from other planets, or internal changes within the planet, such as changes in its mass distribution. Certain events, such as collisions or meteor impacts, can also cause a sudden change in a planet's angular acceleration.
