Are satellites an example of acceleration as it orbits around the earth?
Yes. Since the velocity changes all the time, there is an acceleration. The acceleration is towards the center of the Earth. Note that the speed need not change; velocity consists of a speed (magnitude) and a direction, and in a circular orbit, it is the direction that changes.Yes.

Assume that the moon travel at constant speed in a circular orbit around the earth is the moon's velocity is constant?
Yes, since the moon is in a circular orbit around the Earth, its velocity is constant but its direction is changing continuously as it moves around the Earth. This constant velocity is necessary to maintain the circular motion without drifting away or falling into the Earth.
Why an object in a circular orbit at constant speed is experiencing an accelaratiopn?
An object in circular orbit at constant speed is experiencing an acceleration because the orbit is circular. That is, an object is accelerating not just when its speed is changing but also when its direction is changing. In physics, acceleration refers to a change in velocity which is composed of speed and direction. Hence both a change in speed and a change in direction are, by definition, a form of acceleration.
In what direction is the velocity of the orbiting object?
The velocity of the orbiting object is in the direction tangent to its orbit.
The velocity required to keed a satellite in orbit around the Earth is called?
circular velocity
If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
Not necessarily. A circular orbit around a central body, such as a planet, would also have a radial velocity of zero at all times. In a circular orbit, the satellite's velocity vector is always perpendicular to the radius vector, resulting in a constant radial velocity of zero.
What is the relationship between the velocity of a circular orbit and the gravitational force acting on an object in that orbit?
The velocity of a circular orbit is directly related to the gravitational force acting on an object in that orbit. As the velocity increases, the gravitational force required to keep the object in orbit also increases. This relationship is governed by Newton's law of universal gravitation.
What is an object always changing if it is moving in a circle?
If an object is moving in a circle (like a teather ball or a planet in orbit, although orbit is not a perfect circle), then its velocity is always changing (remember that velocity is speed AND direction, and since the direction is changing, the velocity is changing). It's position is also always changing as a result of having a velocity.
What causes a spaceshuttle to change in velocity by change in direction?
A change in velocity due to a change in direction in a space shuttle is caused by the application of thrust from its engines. By adjusting the direction of thrust, the shuttle can alter its velocity vector, changing its speed and/or direction of travel. This allows the shuttle to adjust its course, orbit, or perform maneuvers in space.
What is the circular orbit velocity formula and how is it used in physics?
The circular orbit velocity formula is v (GM/r), where v is the velocity, G is the gravitational constant, M is the mass of the central object, and r is the distance from the center. This formula is used in physics to calculate the velocity required for an object to stay in a circular orbit around a central mass, such as a planet or a star. It helps scientists understand the dynamics of celestial bodies and spacecraft in orbit.
Is it possible that the velocity of an object be in direction other than the direction of acceleration?
Yes. For example, if you throw a ball straight up in the air, it has a positive initial velocity, but the acceleration due to gravity is in the other direction. From your perspective, until the point when it starts coming back down it will be "decelerating" but really that's just acceleration in the opposite direction of the velocity.
How does the magnitude of the velocity affect a planet's orbit?
The magnitude of a planet's velocity affects the shape and size of its orbit. A higher velocity can cause a planet to move in a more elongated elliptical orbit, while a lower velocity can result in a more circular orbit. The velocity also influences the planet's escape velocity, which determines if it can break free from its orbit.
