Observe the figure and answer the questions.
Sachin and Sameer started on a motorbike from place A, took the turn at B, did a task at C, travelled by the route CD to D and then went on to E. Altogether, they took one hour for this journey.
Find out the actual distance traversed by them and the displacement from A to E. From this, deduce their speed.
What was their velocity from A to E in the direction AE?
Can this velocity be called average velocity?
Explain the following concept in your own words with everyday examples:
Velocity
What is meant by a constant velocity? Is it same as uniform velocity?
Assertion: The Speedometer of a car or a motor-cycle measures its average speed.
Reason: Average velocity is equal to total displacement divided by total time taken.
A body moves with an initial velocity of 5ms-1 and accelerates at 2ms -2. Its velocity after 10s is ______.
If final velocity is equal to initial velocity the value of acceleration is ______.
At the highest point, when a body is thrown vertically upwards, the velocity is ______.
Assertion: A body can have acceleration even if its velocity is zero at a given instant of time.
Reason: A body is momentarily at rest when it reverses its direction of motion.
Give the formula for each.
- elation between initial, final velocity, acceleration, and displacement in a uniformly accelerated straight-line motion.
- Relation between initial, final velocity, acceleration & time in a uniformly accelerated straight-line motion.
- Relation between initial velocity, acceleration, displacement, and time.
Distinguish between speed and velocity.
