How do you find the distance in a circular path?

The distance around a circle is equivalent to a circumference and calculated as 2•pi•R where R is the radius.

What is the distance and displacement of a circle whose radius is R?

Where r is radius of circle. When particle covers half the circle, it is diametrically opposite to the starting point of its motion. Therefore shortest distance is equal to diameter of circle or 2× r is a displacement. Hence displacement is equal to diameter or 2 times the radius of circle.

What is the distance travel by a man if he completes a circular path of radius 7 m?

➟ Distance = 22/7(7) = 22 m. Hence, speed of man is 11/30 m/s.

How do you find the radius in uniform circular motion?

r = m v 2 F c . r = m v 2 F c . From this expression, we see that, for a given mass and velocity, a large centripetal force causes a small radius of curvature—that is, a tight curve. Figure 6.8 In this figure, the frictional force f serves as the centripetal force Fc.

When an object moves on a circular path which has radius r What is the distance traveled by object to complete a round of it?

R is the radius of the circle. The distance travelled by the particle for complete half revolution will be half the circumference. Hence distance travelled will be \[\pi r\]. So, the correct answer is “Option A”.

What will be the distance and displacement when an object moves uniformly on a circle having radius of 7 cm?

Estimate the distance covered and displacement when the particle (i) covers half circular path and (ii) completes the total circular path once. = 2πr=2×227×7=44 cm. Displacement is the length of straight line AB i.e., the diameter of the circle. …

What is the distance Travelled by a body when it moves in a circular path of radius r to complete half revolution?

The displacement of a particle for complete one revolution will be its diameter. Hence displacement will be 2r where, R is the radius of the circle. The distance travelled by the particle for complete half revolution will be half the circumference.

What is the displacement of a half round of a circle?

Correct option is A 2RandπR For completing the half round of circle, the distance covered will be half of circumference of the circle i.e., d=πR. Displacement is the shortest distance between initial and final position, so the displacement will be just the diameter of circle.

What is the distance covered in one round?

Distance covered in one round = Circumference of a circle. Time is taken by an athlete to complete one round = 40 seconds. Displacement in 2 mins that is 120 s will be zero because the athlete will complete 3 rounds and at that time initial position and final position will be the same.

How much time is taken by an athlete to complete one round?

Time is taken by an athlete to complete one round = 40 seconds. Displacement in 2 mins that is 120 s will be zero because the athlete will complete 3 rounds and at that time initial position and final position will be the same. But, later the next 20 s the displacement will be equal to the diameter of the circular track which is 200 m.

What is the distance covered at the end of 2 min 20 seconds?

Hence, the distance covered at the end of 2 min 20 seconds is 2200 m or 22 km. And displacement is 200 m as it returns to the initial position. What is displacement?
