# Why does a satellite in a circular orbit travel at a constant speed? ## Why is the velocity of a satellite in a circular orbit around the Earth constant?

The satellite’s velocity does not change, but its speed (speed and direction) does. Acceleration (as in F=ma ) implies a change in velocity, but not necessarily speed. A circular orbit is an orbit that is exactly balanced so that the velocity never changes.

## When does a satellite travel at a constant speed in a circular orbit? “

A satellite traveling around the Earth in a circular orbit at a constant speed is traveling in a circle. In circular motion, there is a continuous change in direction of motion. As the direction of motion changes, the velocity changes. The rate of change of velocity with respect to time is called acceleration.

## Does an artificial satellite move in a circular orbit at a constant speed? “

Yes, the motion of a satellite around the Earth in a circular orbit accelerates. The acceleration depends on the velocity. Velocity has magnitude and direction. A satellite moves at a uniform velocity, but its direction changes at each point.

## Why does the velocity of a satellite constantly change even though it is moving at a constant speed? “

3A satellite has a constant velocity because it travels the same distance per second as it moves, but its velocity changes because its direction of motion is constantly changing. Since velocity is a vector, when the direction of motion changes, the velocity also changes.

## Why do objects orbiting a planet at a constant velocity still accelerate? “

An object traveling in a circular orbit at a constant velocity has a changing velocity. This is because velocity is a vector quantity that depends on speed and direction. An object in orbit accelerates even though its velocity remains constant because its speed is changing.

## What does an object moving in a circular path with constant velocity have? “

Answer: c. kinetic energy. When a body moves in a circle at a constant velocity, its direction is constantly changing, which means that velocity(v), momentum(p), and acceleration change because they are vectors and their direction changes. only because kinetic energy is a scalar, it remains constant.

## Do satellites have a constant velocity?

Answer and Explanation:A satellite in a circular orbit moves at a constant velocity because during rotation, the direction changes at each instant of time and the velocity remains constant. Velocity is independent of direction, it is a scalar quantity. Velocity depends on direction, it is a vector…

## Why does a satellite have acceleration even though its velocity is constant? “

An object traveling in a circular orbit at a constant velocity has a changing velocity. This is because velocity is a vector quantity that depends on speed and direction. An object in orbit accelerates even though its velocity remains constant because its speed is changing.

## What makes an object move at a constant velocity? “

Newton’s first law of motion explains that if the forces acting on an object are balanced, the object will maintain its state of motion. Maintaining a state of motion means maintaining the current velocity and direction. But if the forces are not balanced, the object will change its state of motion.

## Why do satellites continue to orbit the Earth without changing their velocity? “

The initial velocity of a satellite, maintained when it is detached from the launch vehicle, is enough to keep the satellite in orbit for hundreds of years. A satellite maintains its orbit through the balance of two factors: its velocity (the speed it travels in a straight line) and the Earth’s gravitational pull.

## Why do satellites constantly accelerate? “

Because the initial velocity is less than the escape velocity, the Earth’s gravity constantly pulls the satellite toward the center of the Earth. Therefore, the satellite is constantly accelerating relative to the Earth.

## Centripetal force is the net force acting on an object to keep it moving in a circular path.” Joanna Owens/ author of the article
Hello, everyone! My name is Joanna Owens, and I'm a tourist guide. One of the things that sets me apart as a tourist guide is my enthusiasm and passion for what I do. I believe that travel should be about more than just checking off items on a bucket list; it should be about experiencing new cultures, meeting new people, and discovering the world in all its beauty and complexity. I strive to create tours and experiences that are not only informative but also engaging and interactive, so that my clients can truly immerse themselves in the places they visit.
