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.

Give the direction of velocity of SHM particle.

Assertion: When a particle moves with constant velocity its average velocity, its insttantaneous velocity and its speed are all equal in magnitude. Reason: If the average velocity of a particle moving on a straight line is zero in a time interval, then it is possible that the instantaneous velocity is never zero in the internal.

Assertion: When the body is dropped or thrown horizontally form the same height, it would reach the ground at the same time. Reason: Horizontal velocity has no effect on the vertical direction.

Assertion: In case of projectile motion, acceleration horizontal component of velocity and mechanical energy remains unchanged but speed. Vertical component of velocity, momentum K.E. and P.E. change. Reason: In the presence of air resistance, the range and maximum height attained reduce, but time of flight increases.
