Final answer:

Parabolic motion is the movement along a parabolic path influenced by gravity. Examples include a ball thrown in the air and a projectile fired from a cannon. Calculating the angle for firing a cannon involves using kinematic equations.


Explanation:

Parabolic motion is a form of motion where an object moves in a parabolic path, following the trajectory of a parabola. It combines horizontal motion with constant velocity and vertical motion with constant acceleration due to gravity.

Examples of parabolic motion include a ball thrown in the air, a projectile fired from a cannon, and water from a fountain arcing through the air.

When calculating the angle for firing a cannon to start an avalanche, use kinematic equations to determine the angle that will achieve the desired horizontal distance and vertical height for the projectile path.
