Question

Define projectile. And explain more about it (oblique etc)

Answer 1

$\huge\textbf{Answer}$


» Projectile 


It is a name given to a body thrown with some initial velocity with a horizontal direction and then allowed to move in a two dimensions under the action of gravity alone without being propelled by an external agent.



» Projectile given horizontal projection



1) Path of projectile along x - axis

x = ut

t = x/u ...(1)

• Along y - axis

y = ½ g x²/u²

y = kx² (from 1)

This equation is perabola. Thus path is perabolic.


2) Time of flight

T = √2h/g


3) Horizontal Range

R = u√2h/g


4) Velocity of object at any instant

$v_{x}$ = u

$v_{y}$ = gt

v = √$v_{x}^{2}\:+\:v_{y}^{2}$

v = √u² + g²t²

• direction

β = tan-1 ($v_{x}$$/v_{y}$ )

β = tan-1 (gt/u)



» Oblique projection



1) Path of projectile

• Motion along x - axis

x = (u cosØ) t

t = x/u cosØ ....(1)

• Motion along y - axis

y = (u sinØ) t - ½ gt²

y = u tanØ × ½ g (x²/u² cos²Ø) (from 1)

y = x tanØ - kx²

This equation is perabola and path is perabolic.


2) Time to flight

T = 2u sinØ/g


3) Maximum vertical height

H = u² sin²Ø/2g


4) Horizontal Range

R = u²/g (sin 2Ø)


5) Velocity at any instant

$v_{x}$ = u cosø

$v_{y}$ = $u_{y}\:+\:g_{y}$

v = √$v_{x}^{2}\:+\:v_{y}^{2}$


v = √u² + g²t² - 2u sinØ gt

• direction

tan β = u sinØ - gt/u cosØ

Answer 2

${\huge{\mathrm{\pink{A}{\red{n}{\blue{s}{\orange{w}{\purple{e}{\green{r}}}}}}}}}$

The projectile is any object thrown into space upon which the only acting force is gravity. ... A baseball batted or thrown and the instant the bullet exits the barrel of a gun are all examples of the projectile

It's 3 types : the bullet, the round ball, and shot—are used in muzzleloaders.
