No, projectiles are not always affected by centripetal force. Centripetal force only comes into play when there is circular motion involved. In the case of projectiles, the force of gravity is the dominant force acting on the object.
No, projectiles do not always have a pointed shape. Projectiles can come in various shapes and sizes, depending on their intended use. While some projectiles may have a pointed shape for increased aerodynamics and penetration, others may have a different design to achieve specific effects or functions.
true
No, for instance a warship can fire on the move.
Yes, projectiles are affected by the centripetal force when they are in curved motion. The centripetal force acts towards the center of the curved path, keeping the projectile moving in a circular or curved trajectory.
projectiles can be fin or spin stabilized
No. 38 = .357 projectiles; 380 = .355 projectiles from a shorter case
Because they both propel projectiles at velocities that can cause injury.
No. Missiles are pretty fast but Railgun projectiles are much faster than missiles.
Yea, they can.
The term itself means the study of the motion of projectiles, or the science of designing projectiles for maximum peformance.
HEAT (high explosive antitank) projectiles are specifically designed to attack armored vehicles.
