A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. By definition, a projectile has a single force that acts upon it - the force of gravity.
Any sport where balls are hit, thrown, or kicked is using projectile motion. When an object, like a football, is kicked it becomes a projectile. It then has two velocity components, the speed of it moving vertically and the speed of it moving horizontally.
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.
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.
Understand the motion of projectiles and satellites by separating their motion into horizontal and vertical components for National 5 Physics.
By definition, a projectile is an object upon which the only force is gravity. Gravity, being a vertical force, can only affect the vertical motion of a projectile. As such, the horizontal motion obtained at launch time does not change over the course of the motion.
1 lis 2012 · Projectile motion is movement of an object in a curved path toward the ground because it has both a horizontal force and the downward force of gravity acting on it. Examples of objects that have projectile motion include arrows and cannon balls.
