Question

Q4. Give an example of each:
(i) Acceleration is in the direction of motion.
(ii) Acceleration is against the direction of motion
(iii) Acceleration is uniform.
(iv) Acceleration is non-uniform.
(v) Moving with a constant velocity
(vi) Moving with a changing velocity​

Answer 1

Answer:

1. Any normal moving vehicle with increasing or constant acceleration.

2. Vehicle moving with decreasing acceleration eg.when you hit the brakes but vehicle still moves forward for some time.

3. Constant acceleration without changing of direction eg.a vehicle moving in any one direction.

4. The direction or magnitude might be varying eg.circular motion (direction changes) or object moving with variable acceleration.

5. The direction or magnitude of velocity should not change.

6. The direction or magnitude might be changing.

Answer 2

1-moving of a car in a particular direction with increasing velocity
2-applying brake on the (1example) car.
3-When car is changing velocity .
4-when car is moving with different velocity.
5-displacement is equal in equal interval of time.
6-displacement isunqual in equal time.
