# What is the Radial Acceleration

• Sunnie
In summary, to calculate the radial acceleration of a point on the surface of a planet with a radius of 5.53 x 10^6 m and a rotation period of 24.3 hours, we use the formula (4Pi^2R/T^2). By plugging in the given values, we can find the radial acceleration.

Consider a planet of radius 5.53 106 m with a rotation period of 24.3 hours. Compute the radial acceleration of a point on the surface of the planet at the equator due to its rotation about its axis.

the formula I have is (4Pi^2R/T^2)

Sorry, but what is the radius? 5.53106m? I don't understand what you wrote.

I think Sunnie means the radius is 5.53 x 10^6 m.

If the equation you have given is the correct one for solving this problem then is it not just a case of plugging your values into the equation.

$$\frac{4\pi^{2r}}{t^2}$$

Your value for r is $$5.53\times10^{6}$$

Your value for t is 24.3 hours.

## What is the Radial Acceleration?

The radial acceleration is a measure of the rate at which an object changes its direction while moving in a circular path.

## How is Radial Acceleration different from Tangential Acceleration?

Radial acceleration and tangential acceleration are two components of the total acceleration of an object moving in a circular path. Radial acceleration refers to the change in direction, while tangential acceleration refers to the change in speed.

## What is the formula for Radial Acceleration?

The formula for radial acceleration is a = v^2/r, where "a" is the radial acceleration, "v" is the tangential velocity, and "r" is the radius of the circular path.

## What is the unit of measurement for Radial Acceleration?

The unit of measurement for radial acceleration is meters per second squared (m/s^2).

## How is Radial Acceleration related to Centripetal Acceleration?

Radial acceleration and centripetal acceleration are mathematically equivalent. Centripetal acceleration is the net acceleration towards the center of a circular path, while radial acceleration is the component of that acceleration in a direction perpendicular to the tangential velocity.
