Question

What two factors affect projectile motion? A) distance and angle B) distance and amplitude C) initial velocity and angle D) initial velocity and amplitude

Answer 1

C) Initial velocity and angle

Step-by-step explanation:

The path of the projectile motion is a parabolic path. The motion of a projectile motion is studied by splitting the motion into 2 mutually perpendicular components; one along the horizontal x axis and other vertical y axis.

The position of the projectile at any time
`t` is given as:

`x=ut\cos \theta\\y=ut\sin \theta - (1)/(2)gt^2`

Where,

`u\rightarrow \textrm{Initial velocity}\\v\rightarrow \textrm{Final velocity}\\\theta\rightarrow \textrm{Angle of projection}\\g\rightarrow \textrm{Acceleration due to gravity}`

From the above equations, we conclude that,

The projectile motion depends on two factors:

i. Initial velocity (
`u`)

ii. Angle of projection (
`\theta`)

Option C is correct.
