Projectile Motion

Projectile

A body on free fall that is subject only to the forces of gravity and air resistance.

Influences of Projectile Motion

• Projection angle

• Projection velocity

• Projection height

Projection Angle

The direction at which an object is projected with respect to the horizontal.

Governs the shape of a projectile’s trajectory.

Projectile Velocity

Determines the length of a projectile’s trajectory.

• magnitude

Initial Vertical Magnitude and Direction determines:

• Flight time

• Trajectory

• Vertical displacement

Horizontal Magnitude and Direction determines:

• Horizontal displacement

• Trajectory

Relative Projection Height

Difference between initial projection height and landing height.

Trajectory Factors of Influence

• Projection angle

• Projection initial velocity

• Relative projection height

Flight Time Factors of Influence

• Initial vertical velocity

• Relative projection height

Horizontal Displacement Factors of Influence

• Horizontal velocity (constant)

• Relative projection angle

Vertical Displacement Factors of Influence

• Initial vertical velocity

• Relative projection height
