Question

which of the following statements is not true about projectiles motion A,Horizontal velocity of projectiles is constant B it is a combination of two independent motion-vertical and horizontalC.the motion of the projectile release vertical downward is accelerated D.both horizontal and vertical velocities are constant

Answer 1

The false statement is D.

This comes from the fact that in a projectile motion the weight is acting on the object which means that vertically the force is not zero and in turns this means that vertically the object is accelerating. Since the object is accelerating in this direction the vertical component of the velocity changes in time.
