Assertion: Motion with uniform velocity is always along a straight line path.
Reason: In uniform velocity motion, speed is the magnitude of the velocity and is equal to the instantaneous velocity.
Explanation:
To understand why option B is the correct answer, let's break down the assertion and reason given in the question.
Uniform Velocity:
Uniform velocity refers to the motion of an object in which the object covers equal distances in equal intervals of time. In other words, the object moves with a constant speed in a particular direction.
Assertion Explanation:
Motion with uniform velocity is always along a straight line path.
When an object moves with uniform velocity, it means that its speed and direction do not change. Since the speed remains constant, the object covers equal distances in equal intervals of time. The direction of motion remains the same, and therefore, the object moves along a straight line path.
Reason Explanation:
In uniform velocity motion, speed is the magnitude of the velocity and is equal to the instantaneous velocity.
Velocity is a vector quantity that includes both magnitude (speed) and direction. In the case of uniform velocity motion, the speed remains constant, meaning the magnitude of the velocity remains the same. Therefore, the speed is equal to the instantaneous velocity.
Conclusion:
Both the assertion and reason are true, but the reason does not provide a correct explanation of the assertion. The reason only explains the relationship between speed and velocity in uniform velocity motion, but it does not explain why motion with uniform velocity is always along a straight line path. The straight line path is a consequence of the constant speed and direction in uniform velocity motion. Hence, option B is the correct answer.
Reason: In uniform velocity motion, speed is the magnitude of the velocity and is equal to the instantaneous velocity.
