A bus driver increases the speed of the bus when he starts from Delhi and applies brakes to stop it at Ambala. Discuss the nature of the acceleration in these two cases, assuming the road is straight.

What do you think about the speed of a cyclist having:
1. Acceleration and velocity in opposite directions.
2. Both acceleration and velocity negative.



Answer :

GinnyAnswer

Final answer:

Acceleration direction varies with motion; it can speed up, slow down, or change direction.


Explanation:

Acceleration in the two cases: When the bus driver increases speed from Delhi to Ambala, the acceleration is positive as the speed is increasing. When the driver applies brakes to stop at Ambala, the acceleration is negative as the speed is decreasing.

Speed of a cyclist: (i) If acceleration and velocity are in opposite directions, the cyclist's speed is decreasing. (ii) If both acceleration and velocity are negative, the cyclist is moving in the opposite direction with an increasing speed.

Relation between acceleration and motion: In physics, acceleration doesn't always align with the direction of motion; it can result in speeding up, slowing down, or changing direction.
