"The path of a projectile under gravity is a parabola because it has no horizontal acceleration", Discuss the above statement.

In the motion of a projectile freely under gravity, its

For the motion of a projectile in a vertical plane, horizontal acceleration is ____ and vertical downward acceleration is equal to .

The path of one projectile as seen from another projectile is a (if horizontal components of velocities are equal)

The question given below consist of an assertion and the reason . Use the following key to choose appropriate answer: Assertion: In projectile motion , path followed is a parabola because acceleration due to gravity near the surface of the earth remains constant . Reason , When acceleration of the particle is constant , then only possible path is parabola .

The horizontal range of a projectile is R and the maximum height attained by it is H. A strong wind now beings to blow in the direction of horizontal motion of projectile, giving to constant horizontal acceleration equal to g. Under the same conditions of projections , the new range will be (g = acceleration due to gravity)

The horizontal range of a projectile is R and the maximum height at tained by it is H. A strong windnow begins to blow in the direction of the motion of the projectile, giving it a constant horizontal acceleration = g/2. Under the same conditions of projection, the horizontal range of the projectile will now be:

The horizontal range and miximum height attained by a projectile are R and H , respectively. If a constant horizontal acceleration a = g//4 is imparted to the projectile due to wind, then its horizontal range and maximum height will be

Statement-I : Path of a projectile is a parabola irrespective of its velocity of projection. Statement-II : Trajectory of a projectile is a parabola when variation of g, (acceleration due to gravity) can be neglected.

The trajectory of a projectile fired horizontally with velocity u is parabola given by-
