Assertion : The accelerated motion of an object may be due to change in magnitude of velocity or direction of velocity or both.
Reason : Acceleration can be produed only by change in the magnitude of the velocity.

A

Both assertion and reason are true and reason is the correct explanation of assertion.

B

Both assertion and reason are true but reason is not the correct explanations of assertion.

C

Assertion is true but reason is false.

D

Both assertion and reason is false

The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided, and determine their validity. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "The accelerated motion of an object may be due to change in magnitude of velocity or direction of velocity or both." - Acceleration is defined as the rate of change of velocity. This means that if either the magnitude (speed) of the velocity changes or the direction of the velocity changes, the object is said to be accelerating. 2. **Analyzing the Reason**: - The reason states that "Acceleration can be produced only by change in the magnitude of the velocity." - This statement is incorrect because acceleration can also occur due to a change in the direction of the velocity, even if the speed remains constant. For example, an object moving in a circular path has a constant speed but is accelerating due to the change in direction. 3. **Conclusion**: - Since the assertion is true (as acceleration can result from changes in both magnitude and direction of velocity), and the reason is false (as it limits acceleration to only changes in magnitude), we conclude that: - Assertion is true. - Reason is false. 4. **Final Answer**: The correct option is that the assertion is true, but the reason is false.

What is the direction of velocity and acceleration in shm ?

Assertion : The average speed of an object is greater than or equal to the magnitude of the average velocity over a given time interval. Reason : The two are equal only if the path length is equal to the magnitude of displacement.

Asserion : The acceleration of an object at a particular time is the slope of the velocity-time graph at that instant of time. Reason : For uniform motion acceleration is zero.

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.

Assertion : An object may have varying speed without having varying velocity. Reason : If the velocity is zero at an instant, the acceleration may not be zero at that instant.

How will the equations of motion for an object moving with a uniform velocity change ?

Assertion: In projectile motion, the acceleration is constant in both magnitude and direction but the velocity changes in both magnitude and direction. Reason: When a force or accelration is acting in an oblique direction to the direction of velocity then both magnitude and direction of the velocity may be changed.

Assertion : Magnitude of average velocity is equal to average speed, if velocity is constant. Reson : If velocity is constant, then there is no change in the direction of motion.
