Key Topics to Revise
1
1. Introduction and Basic Concepts
- Projectile motion occurs when an object is launched at an angle to the horizontal under gravity
- Motion is two-dimensional: horizontal (uniform) and vertical (uniformly accelerated)
- Path of projectile is always parabolic for motion near Earth's surface
2
2. Time of Flight, Maximum Height, and Range
- Time of flight (T) is total time projectile remains in air
- Maximum height (H) is highest point reached by projectile
- Range (R) is horizontal distance covered during flight
3
3. Equation of Trajectory
- Trajectory equation relates x and y coordinates at any point
- Eliminates time parameter to get direct x-y relationship
- Confirms parabolic nature of projectile path
4
4. Projectile Motion on Inclined Planes
- More complex than horizontal projection due to inclined landing surface
- Two cases: projection up the plane and down the plane
- Coordinate system aligned with inclined plane simplifies calculations
