When an object moves in a circular path with uniform speed, its motion is called ______.

The correct answer is uniform circular motion.

Key Points

• When an object moves in a circular path with a uniform speed, it is said to be in uniform circular motion.
• In uniform circular motion, the speed of the object remains constant, but the direction of the velocity changes continuously.
• This continuous change in direction means that the object is always undergoing acceleration, even though the speed is constant.
• The acceleration in uniform circular motion is called centripetal acceleration, and it is directed towards the centre of the circular path.
• Examples of uniform circular motion include the motion of a satellite orbiting the Earth, the rotation of a ceiling fan, and the motion of a car turning in a roundabout.

 Additional Information

• Motion along a hemisphere
  • This refers to the motion of an object along the surface of a hemisphere. It is not related to uniform circular motion.
  • Examples might include the motion of a ball on a dome-shaped surface, but it is not uniform circular motion.
• Motion along a straight line
  • This is also known as linear motion or rectilinear motion.
  • In this type of motion, an object moves in a straight path without changing its direction.
  • Examples include a car driving on a straight road or a train moving on straight tracks.
• Linear motion
  • This type of motion refers to the movement of an object in a straight line.
  • Linear motion can be uniform (constant speed) or non-uniform (changing speed).
  • Examples include the motion of a sprinter running on a straight track or an elevator moving up and down.
