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

A large number of particles are moving each with speed v having directions of motion randomly distributed. What is the average relative velocity between any two particles averaged over all the pairs?

Two partcles are projected, between a certain time gap. While both are in air, the velocity of one particle relative to the other:

Statement-1: During flight under action of gravity, the change in velocity of a projectile in same time interval is same. (Neglect air friction) Statement-2: Neglecting air friction, the acceleration of projectile is constant during flight.

In the following questions a statement of assertion (A) is followed by a statement of reason ( R). A : Horizontal metion of projectile without effect of air is uniform motion. R : Without air effect the horizontal acceleration of projectile is zero .

A projectile os shot in air with velocity (v) at an angle theta with the horizontal. Neglecting the air resistance, what are the vertical acceleration and horizontal acceleration at the highest of its fligh ?

Statement-1 : The relative velocity between any two bodies moving in opposite direction is equal to sum of the velocities of two bodies. Statement-2 : Sometimes relative velocity between two bodies is equal to difference in velocities of the two.

Projectile motion is a combination of two one-dimensional motion: one in horizontal and other in vertical direction. Motion in 2D means in a plane. Necessary condition for 2D motion is that the velocity vector is coplanar to the acceleration vector. In case of projectile motion, the angle between velocity and acceleration will be 0^@ltthetalt180^@ . During the projectile motion, the horizontal component of velocity ramains unchanged but the vertical component of velocity is time dependent. Now answer the following questions: A particle is projected from the origin in the x-y plane. The acceleration of particle in negative y-direction is alpha . If equation of path of the particle is y = ax - bx^2 , then initial velocity of the particle is

Assertion : Particle A is moving Eastwards and particle B Northwards with same speed. Then, velocity of A with respect to B is in South-East direction. Reason : Relative velocity between them is zero as their speeds are same.
