It is a vector quantity. For example, if a body moves along a circle of radius r and covers half the circumference, then displacement is given by s=2r . In one-dimensional motion displacement of the object will be the shortest distance between final and initial point.
How do you find the distance of a circular path?
The distance around a circle is equivalent to a circumference and calculated as 2•pi•R where R is the radius . The time for one revolution around the circle is referred to as the period and denoted by the symbol T. Thus the average speed of an object in circular motion is given by the expression 2•pi•R / T.
What is the displacement of a circular path?
Hint: Displacement is the shortest distance between two points , i.e., between the starting point and the ending point. It is independent of the path taken by an object. The circle after one cycle has the same starting and ending point.
How do you find distance and displacement?
Answer: Starting position, s_i = 0. His final position s_f is the distance traveled North minus the distance traveled South. Calculating displacement, s = s_f – s_i .
How do you find a circular displacement?
In simpler words, the displacement of an object is the distance travelled by it around the circumference of a circle divided by its radius .
What is the formula of circular motion?
| Equation Symbol breakdown | v = r ω v = r omega v=rω v v v is linear speed, r is radius, ω is angular speed. | T = 2 π ω = 1 f T = dfrac{2pi}{omega} = dfrac{1}{f} T=ω2π=f1 T T T is period, ω is angular speed, and f is frequency |

What is the displacement of a straight line?
The displacement of a particle moving in a straight line is the change in its position . If the particle moves from the position x(t1) to the position x(t2), then its displacement is x(t2)−x(t1) over the time interval [t1,t2]. ... If a particle moves from O to B, its displacement is 3 m.
What are the similarities between distance and displacement?
In physics, distance and displacement are used to indicate the length between two points . However, these two are not one and the same thing. While distance is the length of the actual path between two locations, displacement, on the other hand, is the length of the shortest path between two locations.
How do you find displacement with distance and time?
The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = 1⁄2( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.
What is linear displacement in circular motion?
The motion of an object along a curved path is studied under circular motion or curvilinear motion. In the case of linear motion, the difference between the initial point and final point is termed as displacement.
How do you find the displacement of an angle?
Angular displacement is defined as “ the angle in radians (degrees, revolutions) through which a point or line has been rotated in a specified sense about a specified axis”. It is the angle of the movement of a body in a circular path.
What is angular displacement in simple words?
Angular displacement of a body is the angle in radians, degrees or revolutions through which a point revolves around a centre or a specified axis in a specified sense . ... Thus the rotation of a rigid body over a fixed axis
What is circular motion class 9?
Uniform Circular Motion (UCM) When a body moves in a circle , it is called circular motion. When a body moves in a circular path with uniform speed (constant speed), its motion is called Uniform Circular motion (UCM).
