Projectile motion. Parabolic trajectories of water jets. Components of initial velocity of parabolic throwing. Ballistic trajectories are parabolic if gravity is homogeneous and elliptic if it is radial. Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as ...
In physics, a projectile launched with specific initial conditions will have a range. It may be more predictable assuming a flat Earth with a uniform gravity field, and no air resistance. The horizontal ranges of a projectile are equal for two complementary angles of projection with the same velocity. The following applies for ranges which are ...
A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously. The mass might be a projectile or a ...
External ballistics. This schlieren image of a bullet travelling in free-flight demonstrates the air-pressure dynamics surrounding the bullet. External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin ...
Ballistic coefficient. A selection of bullets with different shapes, and hence, different ballistic coefficients. In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative ...
A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. [1][2] Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow ...
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
The motion of a bouncing ball obeys projectile motion. [2] [3] Many forces act on a real ball, namely the gravitational force (F G), the drag force due to air resistance (F D), the Magnus force due to the ball's spin (F M), and the buoyant force (F B). In general, one has to use Newton's second law taking all forces into account to analyze the ...
