Position, Path Length and Displacement: Overview
This topic consists of various concepts like Basic Definitions of Motion,Motion and Rest,Position of Body, etc.
Important Questions on Position, Path Length and Displacement
The displacement of particle moving in one dimension, under the action of a constant force is related to the time by the equation where is in meters and in seconds. Find the displacement of the particle when its velocity is zero.

A particle moves in a circle of radius Find its displacement and the distance covered for half the period of its revolution.

A boy moves from A to B through , B to C through and again from C to D through . Find his displacement.

Define motion.

A particle moving along the path , from to . Then the distance travelled by the particle is

A disc is rolling without slipping on a surface. The radius of the disc is At the top most point on the disc is as shown in figure. When the disc completes half of its rotation, the displacement of point from its initial position is

Two particles move from A to C and A to D on a circle of radius R and diameter AB. If the time taken by both particles are the same, then the ratio of magnitudes of their average velocities is

In one second, a particle goes from point A to B moving in along circle shown in figure. The magnitude of its average velocity is

If position of a particle is , find distance and displacement at .

The combined frictional and air resistance on a bicyclist has the force, where v is his velocity and . At maximum effort, the cyclist can generate propulsive power. What is his maximum speed (in ) on level ground with no wind?

Figure shows the time-displacement curve of the particles P and Q. Which of the following statement is correct?

A body is moving along the circumference of a circle of radius R and completes half of the revolution. Then, the ratio of the displacement to distance is

An insect can crawl on the floor. If it starts crawling from one corner of a cubical room of slde '' Minimum distance it would crawl to raech the furthermost corner in the room.

The position time graph for a particle moving on -axis is shown here. Choose correct statement.

A frog takes leaps in forward direction and leaps backward. A pot hole is a head of the frog. If the distance covered in leap is . Find the distance travelled by frog before it falls in the pothole.

An aeroplane is flying from city to city along path . The path is a circular arc whose centre coincides with the centre of the Earth. Another aeroplane is flying along path from to . The path is circular arc whose centre is at is the centre of the Earth. Then,

A person runs along a circular path of radius . If he completes half of the circle find the magnitude of the displacement vector. How far the person ran?

A motorist travelled from town A To Town B at an average speed of . On his return journey, he travelled his average speed with . If the total time taken is , find the distance between the two towns.

Let and be the positions of an object at time and . Then, its displacement, denoted by A, in time , is given by the difference between the C and D position.
Here A,B,C and D refer to
