# What Causes A Satellite To Move Tangentially To A Circular Path??

Tangential speed changes throughout a satellite’s orbit. Centripetal force is perpendicular to the velocity of the satellite. Tangential speed increases with a satellite’s increasing distance from Earth. Centripetal force can sometimes slow down a satellite in orbit.

## Why does an object moving in a circular path have an acceleration?

Acceleration is a change in velocity, either in its magnitude—i.e., speed—or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant.

## Why do objects move in circular orbit?

The direction of the net force is in the same direction as the acceleration. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the centripetal force requirement.

## What force is needed to keep an object moving in a circle?

A centripetal force is a net force that acts on an object to keep it moving along a circular path.

## What must be true of a force that causes an object to move in a circular motion?

What must be true of a force that causes an object to move in a circular motion? It acts parallel to the velocity and is directed toward the center of the circle.

## Which force is responsible for circular?

centripetal force.

## What forces are responsible for circular motion?

A centripetal force is a net force that acts on an object to keep it moving along a circular path.

## What is responsible for the centripetal force in the motion of an electron around the nucleus?

Answer: The charge of the nucleus is positive and the charge of the electron is negative. There exists an electrostatic force between the positive nucleus and negative electrons. This electrostatic force supplies the necessary centripetal force for revolving of electrons around the nucleus.

## Why does an object in orbit move in a circular path?

Velocity, Acceleration and Force Vectors And this acceleration is caused by a net force that is directed inwards in the same direction as the acceleration. This centripetal force is supplied by gravity - the force that universally acts at a distance between any two objects that have mass.

## What causes an object to move in circular motion?

So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the centripetal force requirement. The word centripetal (not to be confused with the F-word centrifugal) means center seeking.

## Where is the force in circular motion?

Any object moving in a circle (or along a circular path) experiences a centripetal force. That is, there is some physical force pushing or pulling the object towards the center of the circle. This is the centripetal force requirement.
