Want this question answered?
-- Gravity causes the vertical component of projectile motion to vary according to the local acceleration of gravity. -- Gravity has no effect at all on the horizontal component of projectile motion.
All that I can think of are: 1.) Gravity 2.) Wind 2.A) wind speed 2.B) direction of wind 3.) Angle of trajectory 4.) Initial speed of projectile 5.) Material through which projectile travels (as in density) 6.) Mass of projectile 7.) Spin 7.A) speed of spin 7.B) axis/axes spining occurs on 8.) Shape of projectile 9.) Temperature of medium projectile is in 10.) Size of projectile (as in height, width, and depth) 11.) Weighting of projectile 12.) Obsturctions to projectile's path In a vaccuum, though, these are the variables: 1.) Speed of object 2.) Obstructions in path 3.) Gravity
A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.
A projectile is an object moving through the air but people mainly think of a projectile as something you aim at someone and attempt to hit them with. A rock, a bullet, an arrow, a missle, all can be considered projectiles. The first sentence of the answer though is what you are looking for I think.
-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.
A projectile need not revolve at all in order to be a projectile.
-- Gravity causes the vertical component of projectile motion to vary according to the local acceleration of gravity. -- Gravity has no effect at all on the horizontal component of projectile motion.
Projectile motion is a form of motion wherein an object moves along a curved path under the action of gravity only. The height of a projectile in motion is dependent on gravity.
Almost all of the aplicants that apply to a highly selective college do not get admitted.
Either is correct, but the particular choice will depend on the usage. Only one is correct for a given application. Let's look at a couple of examples and see how each is used."We are seeking a housekeeping supervisor, and any person with a year experience is encouraged to apply.""We are seeking a housekeeping supervisor and all persons with a year of experience are encouraged to apply."The examples are compound sentences, as you can see. The relative portion of the examples is the latter one, and here they are broken out:"Any person with a year of experience isencouraged to apply.""All persons with a year of experience areencouraged to apply."In the examples, we see that "... person ... is..." and "... persons ... are ..." both meet the demands of proper English usage.
Any shape you like. A stone that is thrown is a projectile. A cannonball, arrow, spear, bullet are all projectiles. A projectile s an object all of whose momentum comes at the moment of launch; once it is launched, it travels under that initial momentum and external forces such as gravity and air resistance. There is no "on board" rocket or other means of propulsion.
