Question

in horizontal projectile motion, is the initial velocity actually the vertical velocity?

Answer 1

Dear Student

• A projectile is any object upon which the only force is gravity,
• There are no horizontal forces acting upon projectiles and thus no horizontal acceleration,
• The horizontal velocity of a projectile is constant (a never changing in value),
• There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down,
• The vertical velocity of a projectile changes by 9.8 m/s each second,
• The horizontal motion of a projectile is independent of its vertical motion.

This means that initial velocity has two components horizontal and vertical components.
