Projectile motion is the motion of an object that is thrown or launched into the air and moves along a curved path due to the force of gravity. It happens when an object has an initial forward velocity and is pulled downward by gravity, causing it to follow a predictable arc-shaped path. The meaning of PROJECTILE is a body projected by external force and continuing in motion by its own inertia; especially : a missile for a weapon (such as a firearm).
Any object thrown, kicked, shot, or dropped at an angle — a ball, bullet, long-jumper, water stream — undergoes projectile motion if air resistance is negligible. In physics, projectile motion describes the motion of an object that is launched into the air and moves under the influence of gravity alone, with air resistance neglected. Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. Blast a car out of a cannon, and challenge yourself to hit a target!
projectile motion phet, Learn about projectile motion by firing various objects. Set parameters such as angle, initial speed, and mass. Explore vector representations, and add air resistance to investigate the factors that influence drag. Most projectile weapons use the compression or expansion of gases as their motive force. Blowguns and pneumatic rifles use compressed gases, while most other guns and cannons utilize expanding gases liberated by sudden chemical reactions by propellants like smokeless powder.
projectile motion phet, The simple definition of PROJECTILE is something (such as a bullet or rocket) that is shot from a weapon.
