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?
A body goes from A to B with a velocity of 30 ms-1 and comes back from B to A with a velocity of 20 ms-1. What is the average velocity of the body for the whole journey?
A body moves along a straight track. Half of the distance it covers with a velocity of 40 ms-1 and the remaining half with a velocity of 60 ms-1. What is the average velocity for the whole journey?
The graph shows how the velocity of a scooter varies with time in 50 s. Interpret the graph.
Exercise Problems.
A ball is gently dropped from a height of 20 m. If its velocity increases uniformly at the rate of 10 ms–2, with what velocity will it strike the ground? After what time will it strike the ground?
The equation v = u + at gives information as ______.
If the velocity of the body decreases with time the acceleration is negative and the motion is called decelerated 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.
Define velocity.
Distinguish between speed and velocity.
