Week 26 - Projectile Motion Flashcards
was is the constant of acceleration ?
-9.81 m/s^2
define projectile
a body undergoing projectile motion
define gravity
the attraction influence that pulls an object to its surface
define air resistance
limits the motion of a projectile
define trajectory
flight path of a projectile through the air
define parabola
trajectory follows a ‘parabolic’ curved shape that is symmetrical about its apaex
define apex
highest point reached by a projectile
define range
horizontal displacement of projectile
what 3 factors influence projectile motion ?
- projection angle
- projection velocity
- projection height
what does the angle at release determine ?
the shape of the trajectory
what does the projection velocity determine ?
the height and range of a projectile
define vertical velocity
determines height and time of flight
define horizontal velocity
determines range
define projection height
the relative difference in height between release and landing (vertical displacement)
projection height = 0
- height release is the same as landing
- symmetrical, parabolic trajectory
