Projectile Motion Model: Model Development & Motion

Sections 5.1 & 5.2

What does projectile motion mean?

Projectile = An object that is projected such that it remains near Earth’s surface and air resistance is negligible

Motion = the position is changing

What are the assumptions for the Projectile Motion Model?

Particle, 2D motion, constant horizontal velocity, constant downward acceleration, neglect air resistance

In addition to the assumptions, you must include these in your interpret step:

Neglect Earth’s curvature

Neglect Earth’s rotation

The horizontal velocity does not change; thus,

a_x = 0

The vertical velocity does change
