Projectile Motion

Question 1

combination of two linear motions
if assuming no air resistance, there is no acceleration in the horizontal (x) direction (velocity is constant)
acceleration due to gravity in y direction
at max height, velocity in the y direction = 0

Answer 1

projectile motion

Question 2

2 variables determined by y component in projectile motion

Answer 2

time in air

maximum height

Question 3

variables determined by x component in projectile motion

Answer 3

range

Question 4

acceleration due to gravity

Answer 4

10 m/s^2 downward

Question 5

use the _______ to find the time of a projectile in the air

Answer 5

velocity in the y direction

Question 6

to find the initial velocity of a projectile as it moves through the air, separate the initial velocity into _____ using SOH CAH TOA. Use linear motion equations to find the time it take for an oject to reach max height. ______ that time to find the total time of that object in flight.

Answer 6

x and y components

double

Question 7

the __________ velocity of a projectile is constant and determines only the ______ of the object

Answer 7

horizontal

range

Question 8

the _______ velocity of a projectile is changing at a rate of 10 m/s^2 (toward Earth) and = 0 m/s at the object’s mass height
This determine’s the object’s time in the air and its maximum height

Answer 8

vertical (velocity in y direction)

Question 9

Equation: Range of a projectile (distance traveled in horizontal direction) using horizontal velocity and time

Answer 9

range = horizontal velocity * time in flight
x = V(x) * (t)
Note: t = 2 x time it takes for projectile to reach max height

Question 10

Three steps for projectile motion equations:

Answer 10

1. Figure out initial y and x components of Velocity using SOH CAH TOA
2. Use y velocity to find time in air
3. Multiply time in air times horizontal velocity to find range (distance traveled in x direction) of the projectile
