What does the odometer of an automobile measure?

Does the motion of second’s hand of a watch represent uniform velocity or uniform speed?

Plot the v-t graph for the following data and state the nature of motion the body:

Give one example each of uniform and non uniform in our daily life.

Instruction: The table given below shows distance (in cm) travelled by the bodies A, B and C. Read this data carefully and answer the questions which follow.

Distance (in cm) covered by different bodies

1. Which of the bodies is moving with

(a) constant speed?

(b) constant acceleration?

2. Which of the bodies covers

(a) maximum distance in 3^rd second?

(b) minimum distance in 3^rd second?

3. Which of the bodies is moving with non-uniform acceleration?

Write true or false for the following statements:

Acceleration is defined as the rate of change of velocity.

Write true or false for the following statements:

A motion is said to be uniform, if x t²

Write true or false for the following statements:

A motion is said to be uniform, if a body undergoes equal displacements in equal intervals of time.

Write true or false for the following statements:

The motion in animals is called locomotion. Mechanics deals with the motion of non-living objects.

Write true or false for the following statements:

A body is said to be at rest, if it does not change its position with respect to the reference point.

Which of the following statement is correct regarding velocity and speed of a moving body?

A. velocity of a moving body is always higher than its speed

B. speed of a moving body is always higher than its velocity

C. speed of a moving body is its velocity in a given direction

D. velocity of a moving body is its speed in a given direction.
