And that centripetal acceleration is the acceleration due to gravity

So that's centripetal force causing centripetal acceleration which causes the object to go towards the center

Another situation like this, once again this involves centripetal acceleration, inward forces, inward acceleration.

What I want to do in this video is a calculus proof of the famous centripetal acceleration formula that tells us the magnitude of centripetal acceleration, the actual direction will change it's always going to be pointing inwards, but the magnitude of centripetal acceleration is equal to the magnitude of the velocity squared divided by the radius

We'll do more videos on intuition of centripetal acceleration and centripetal forces, inward forces, if this does not make complete intuitive sense for you at this moment.

So calculating the altitude simplifies into calculating the point where the magnitudes of the centripetal acceleration required for orbital motion and the gravitational acceleration provided by Earth's gravity are equal.

Centripetal

The magnitude of the centripetal acceleration is equal to your speed, the magnitude of your velocity, squared, divided by your radius.

In fact if you did not have gravity which is causing the centripetal acceleration it would just go in a straight path forever and ever

Earth orbit A spacecraft enters orbit when it has enough horizontal velocity for its centripetal acceleration due to gravity to be less than or equal to the centrifugal acceleration due to the horizontal component of its velocity.

So if we square it, this is going to be (v over r) squared, now we saw that in the video on angular velocity, times r and this is all going to be the magnitude of our acceleration, which is really our centripetal acceleration, our inward directed acceleration.

So we know that the magnitude of your centripetal acceleration is going to be equal to your speed squared divided by the radius of the circle that you are going around

So we know from our studies of circular motion so far what's keeping it going in circular motion assuming that it has a constant speed is some type of centripetal acceleration

And this force is called the centripetal force

And in the next video we'll figure out how fast does it have to travel in order to stay in orbit, in order for it not to plummet to Earth due to the force of gravity, due to the acceleration that is occurring, this centripetal, center seeking acceleration.

So it measures acceleration, angular acceleration

If you speed up a lot beyond that speed, you will slowly spiral away from the Earth because then the centripetal acceleration due to gravity won't be enough to keep you in a perfect circular path

That equals acceleration times time what's the acceleration?

Force Mass times acceleration acceleration and force are vector quantities

So the acceleration, and once again, acceleration is a vector quantity.

A is acceleration.

This is acceleration.

So it measures acceleration, angular acceleration like a human ear, inner ear.

So, is acceleration happening?

We've added Hardware Acceleration.

Now, what's its acceleration?

In physics, gravitational acceleration is the acceleration on an object caused by force of gravitation.

Centripetal force, centri you might recognize as center and then petal is seeking the center.

So we know the acceleration.

Acceleration is a vector quantity.
