If the object in uniform circular motion is accelerating towards the center of the circle, why does it maintain a circular path at a constant radius and never get closer to the center of the circle?



Sagot :

If the object in uniform circular motion is accelerating towards the center of the circle it maintains a circular path at a constant radius and never gets closer to the center of the circle. The force of gravity stay at 90 degrees relative to its motion. Therefore an object undergoing uniform circular motion is moving at a constant speed. Nonetheless, it is accelerating due to its shift in direction. Yet, with the centripetal force directed perpendicular to the velocity, the object changes its direction and experiences an centripetal acceleration.

Types of Circular Motion

There are two different types of circular motion namely:

  • Uniform circular motion is a situation where the angular speed and acceleration are constant but angular velocity changes.
  • Non-uniform circular motion occurs when angular speed and velocity also changes with constant angular acceleration.

Examples of Circular Motion

Examples of circular motion include:

  1. A man-made satellite orbiting the Earth at a constant height.
  2. A stone tied to a rope and is being swung in circles.
  3. A car moving through a curve in a race track.
  4. An electron traveling perpendicular to a unchanging magnetic field.
  5. A gear going inside a mechanism.
