Assertion: In projectile motion, the vertical velocity of the particle is continoulsy decreased during its ascending motion. Reason: In projectile motion downward constant acceleration is present in vertical direction.

A force-time graph for the motion of a body is shown in fig. change in linear momentum between 0 and 8 s is:-

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 a particle is projected at some angle from horizontal. At highest point of its path radius of curvature is least. At highest point of path normal acceleration of projectile is equal to acceleration due to gravity.

Assertion: The path of one projectile as seen for another projectile is a striaght line. Reason: Two projectiles projected with same speed at angles alpha and (90^(@)-alpha) have same range.

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.

Assertion : The force of tension on a body always act away from the body. Reason: Friction force always opposes the motion of a body.

Assertion: In projectile motion horizontal velocity remains same but vertical velocity continously change and particle strikes the ground with same vertical velocity with which the particle was thrwon in vertical direction.

Assertion: Projectile motion is uniformly accelerated motion. (Neglect the effect of air. ) Reason: In projectile motion, speed remains constant.

Assertion: A negative acceleration of a body can be associated with a 'speeding up' of the body. Reason: Increase in speed of a moving body is independent of its direction of motion.
