Assertion If in a projectile motion, we take air friction into consideration, then `t_("ascent") lt t_("descent")`.
Reason During ascent, magnitude of retardation is greater than magnitude of acceleration during descent.

A

If both Asseration and Reason are correct and Reason is the correct explanation of Assertion

B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion

C

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five reponses (a) If both Assertion and Reason arecorrect and Reason is the correct explanation of Asserrtion. (b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. (c ) If Assertion is true but Reason is false. (d) If Assertion is false but Reason is true. Assertion In projectile motion, the rate of change in magnitude of potential energy of a particle first decreases and then increases during motion. Reason In projectile motion, the rate of change in linear momentum of a particle remains constant during motion.

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following four responses Assertion A particle is thrown vertically upwards. If air resistance is taken into consideration then retardation in upward journey is more than the acceleration in downward journey. Reason Some mechanical energy is lost in the form of heat due to air friction.

  • 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 : In projectile motion at any two positions (v_2-v_1)/(t_2 -t_1) always remains constant. Reason : The given quantity is average acceleration, which should remain constant as acceleration is constant.

    Assertion: if air resistance is considerd then time to ascent and time of desent will be different. Reason: Magnitudes of acceleration will be different in upwards and downward motion.

    Assertion In case of projectile motion, the magnitude of rate of change of velocity is variable. Reason In projectile motion, magnitude of velocity first decreases and then increases during the motion.

    Assertion In projectile motion, the angle between instanteneous velocity vector and acceleration vector can be anything between o to pi (excluding the limiting case) Reason In projectile motion, acceleration vector is always pointing vertically downwards. (Neglect air friction.)

    Assertion : Kinematic equations are exact and are always correct. Reason : The definitions of instantaneous velocity and acceleration are true only for motion in which the magnitude and direction of acceleration are constant during the course of motion.
