The curved path that an object follows when thrown, launched, or otherwise projected near the surface of the Earth.

• Resultant vector

• Parabolic motion

• Projectile motion

• Circular motion

A movement of an object along the circumference of a circle or rotation along a circular path.

• Free fall

• Parabolic motion

• Circular motion

• Projectile motion

How much time the projectile spends in the air.

• Trajectory

• Flight (hang) time

• Range

• Launch angle

The angle from the ground that a projectile is launched into the air. Can be from 0 to 90 degrees. Helps determine the range, height, and time of flight.

• Launch angle

• Trajectory

• Range

• Projectile angle

The parabolic path of a projectile through the air.

• Launch angle

• Range

• Trajectory

• Horizontal range

Free fall with an initial velocity

• Air resistance

• Horizontal motion

• Freefall

• Projectile motion

Represents the sum of two or more vectors.

• Vertical vector

• Resultant vector

• Horizontal vector

• Parabolic vector

An object that is thrown or launched into the air.
