Speed, compared to what? The Sun's apparent speed in the sky, from our point of view, is approximately 15 degrees an hour. The Sun's speed around the center of the Milky Way is approximately 220 km/second. I believe that most of that is tangential speed.

What 2 forces combine to keep a planet in orbit?
There are two factors; the tangential velocity, and the gravitational force. The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force is constantly attracting the planets in, against this tangential velocity. If the planets were to slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.
What is the SI unit for tangential speed?
meters per second
Does the suns gravity keep the planets from floating away?
The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force attracts the planets in, against this tangential velocity. If the planets were to gradually slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.
Why don't planets move all the way into the sun?
Because they're moving too fast in the tangential direction. As they fall towards the sun they travel tangentially just enough that they never get too close to the sun.
Why do not the planets collide with the sun due to gravitational force?
They have a sideways speed, a tangential velocity which prevents them from falling into the sun. The whole solar system has this rotational spin, that has been around since it's formation as the gases and other material that makes up our solar system came together. It won't slow down due to friction as there is no friction in the vacuum of space.
Relationship between tangential speed and distance from the center of r?
tangential speed is directly proportional to rotational speed at nay fixed distance from the axis of rotation
What is the unit of tangential speed and linear speed?
Tangential speed is how fast a point on a circular object is moving at a certain distance from the center whereas rotational speed is how many degrees (or radians) a point on the circle goes through in a period of time. Every point on a circle has the same rotational speed. The further out you go from the center, the higher the tangential speed is.
What is linear speed called when something moves in a circle?
Tangential speed
What happens to tangential speed as rotational speed increases?
we can say that tangential speed of the object is linearly proportional to the distance from the center. Increase in the distance results in the increase in the amount of speed. As we move to the center speed decreases, and at the center speed becomes zero.
What keeps a planet in its constant orbit?
There are two factors that are balanced just right to keep the planets in their orbits; the tangential velocity, and the gravity. The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force is constantly attracting the planets in, against this tangential velocity. If the planets were to slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.

What keeps mars in orbit around the sun?
The Sun's gravity combined with the tangential ("sideways") velocity of Mars.

Why does it take less than 365 earth days for mercury and venus to complete one revolution around the sun?
Mercury and Venus take less time to complete one orbit of the sun, since they are closer to the sun. They have less distance to travel, and are orbiting at a greater tangential speed.
Why did the cat fall to earth instead of rising up to moon?
because of tangential speed
What state has the greatest tangential speed?
Texas because Texas has the most penises
