The angle, with the horizontal, at which a projectile is projected, is known as angle of projection.

A path, traced by a projectile in the space, is known as trajectory.

The velocity, with which a projectile is projected, is known as the velocity of projection.

Both (A) and (B)

Angle of inclination of the plane

None of these

Angle of projection

y = (gx²/2u² cos²α) - x. tanα

y = x. tanα + (gx²/2u² cos²α)

y = (gx²/2u² cos²α) + x. tanα

y = x. tanα - (gx²/2u² cos²α)
