Anything that travels through the air without guiding its flight is a projectile. Examples include a spear, arrow,bullet, cannonball, model rocket, baseball, football, skydiver. Non-projectiles are parachutes, airplanes, helicopters, gliders, birds when flying. Air resistance is a factor in a projectile's flight. However, at this level of physics, air resistance, also called "drag," will always be ignored.
Projectile motion problems are kinematics problems in 2 dimensions.
When solving projectile motion problems always:
- Be clear in your solution and use lots of space on your paper. Conserving paper will cost you points because it makes for poor communication. Plan on using a page for each problem's solution.
- Draw and label a picture
- List the given in a clear table
- Show your requations
- If needed, insert an equation into another equation before replacing variables with numbers and units, (like in example 1 below.)
