what are horizontal and vertical component of acceleration of a body thrown horizontally with uniform speed.

When a particle is projected with an initial velocity to an angle θ with horizontal then its has two components one along horizontal and one along vertical.

Horizontal component = = .

Vertical component = = .

The horizontal component remains unchanged as there is no net force acting in that direction and this component gives the particle a horizontal displacement.

The vertical component initially decreases as force of gravity is acting in downward direction and at maximum height it becomes zero.This component gives a vertical displacement to particle.

Both components gives the particle a two dimensional motion  called a projectile motion.

Sine the speed is uniform, the acc.in horizontal direction is ZERO.

The vertical component will be 9.8 m/s (g) as gravity always acta on a body in downward direction.
