Study Notes
Projectile Motion
- Projectiles launched at an angle involve a combination of upward motion (affected by gravity) and horizontal motion.
- The height and range of a projectile depend on its launch angle and initial velocity.
- Acceleration due to gravity is constant (-9.81 m/s²) and always directed downwards.
- Directions are crucial in projectile motion problems.
- Positive and negative numbers are used to indicate the direction of motion.
Pool Ball Example
- A pool ball leaves a 1-meter high table with an initial horizontal velocity of 2.4 m/s.
- Calculate the time the ball stays in the air.
- Calculate the horizontal distance the ball travels before landing.
Angle and Maximum Height/Range
- To maximize height, launch at a 90-degree angle.
- To maximize range, launch at an angle between 45 and 48 degrees (optimum angle depends on other factors)
