Projectile Motion

what is a projectile?

a body in free fall that is subject only to the forces of gravity and air resistance

what is projectile motion?

a special case of linear motion therefore the same principles of displacement, velocity and acceleration still apply

what do the horizontal and vertical components of a projectile relate to?

horizontal: distance traveled

vertical: maximum height achieved

what influences projectile trajectory?

1. projection angle

2. projection velocity

3. projection height

what is the projection angle responsible for?

trajectory shape

what is the projection velocity responsible for?

size of trajectory

what is the projection height responsible for?

maximum height something will reach

what are the three trajectory shapes?

vertical, parabolic and ½ parabolic

for a body projected vertically upward, the projectile’s … determines the height of the trajectory’s apex.

initial velocity

for a body projected with an oblique angle, the initial velocity determines…

both the vertical and horizontal length of the trajectory

magnitude and direction of initial vertical component of velocity determines…?

flight time, trajectory ad vertical displacement

magnitude and direction of horizontal component of velocity determines…?

horizontal displacement and trajectory

what is relative projection height?

the difference between projection height and landing height

what are the factors of influence for flight time?

initial vertical velocity and relative projection height

what factors influence horizontal displacement?

horizontal velocity (constant) and relative projection angle

what influences vertical displacement?

initial vertical velocity and relative projection height
