Assertion: Momentum of an object which is the product of mass and velocity is a vector quantity.
Reason: Momentum has both direction as well as magnitude.
The correct answer is option 'A' - Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Explanation:
Definition of Momentum:
Momentum is defined as the product of an object's mass and velocity. It is a vector quantity, which means it has both magnitude and direction.
Assertion (A): Momentum of an object which is the product of mass and velocity is a vector quantity.
Momentum is indeed a vector quantity because it possesses both magnitude and direction. The direction of momentum is the same as the direction of the velocity of the object.
Reason (R): Momentum has both direction as well as magnitude.
This statement is a correct explanation of the assertion. Momentum is not only about the quantity of motion (magnitude) but also about the direction of motion. The direction of momentum is determined by the direction of the velocity of the object.
Example:
To further understand the concept, let's consider an example. Suppose a car is moving towards the east with a velocity of 20 m/s. If the car has a mass of 1000 kg, we can calculate its momentum as follows:
Momentum = mass × velocity
Momentum = 1000 kg × 20 m/s = 20,000 kg·m/s towards the east.
Here, we can see that momentum is not only a numerical value (magnitude) but also has a specific direction (east in this case). Therefore, momentum is a vector quantity.
Conclusion:
Momentum is a vector quantity because it possesses both magnitude and direction. The direction of momentum is the same as the direction of the velocity of the object. Therefore, both the assertion and the reason are correct, and the reason provides the correct explanation for the assertion.
Reason: Momentum has both direction as well as magnitude.
The correct answer is option 'A' - Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

Reason (R): Momentum has both direction as well as magnitude.
This statement is a correct explanation of the assertion. Momentum is not only about the quantity of motion (magnitude) but also about the direction of motion. The direction of momentum is determined by the direction of the velocity of the object.
Example:
To further understand the concept, let's consider an example. Suppose a car is moving towards the east with a velocity of 20 m/s. If the car has a mass of 1000 kg, we can calculate its momentum as follows:
Momentum = mass × velocity
Momentum = 1000 kg × 20 m/s = 20,000 kg·m/s towards the east.

Conclusion:
Momentum is a vector quantity because it possesses both magnitude and direction. The direction of momentum is the same as the direction of the velocity of the object. Therefore, both the assertion and the reason are correct, and the reason provides the correct explanation for the assertion.
