0.4 (a) Is uniform circular motion accelerated motion?
(b) When is a body said to have uniform velocity?
(c) How can we describe the position of an object?
Illustrate with suitable example.
Answers
Explanation:
Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle.
To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction
Which statement is true about an object that is traveling in uniform circular motion? The speed of the object varies. The net force on the object is directed toward the center of the circular path. The direction of the object's velocity is constant.
Answer:
1...An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction.
2..A body is said to have uniform velocity when the body is travelling equal distance in equal interval of time , in a particular direction.
3 ..we can describe the postion of an object, by using reference point called the origin
