Understanding Projectile Motion

Projectile motion is a form of motion experienced by an object or particle (a projectile) that is thrown near the Earth’s surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible).

Physics Formulas Used (Simple Mode)
  • Horizontal Distance (x): \( x = v_0 \cdot \cos(\theta) \cdot t \)
  • Vertical Position (y): \( y = h_0 + v_0 \cdot \sin(\theta) \cdot t – \frac{1}{2}gt^2 \)
  • Time to Max Height: \( t_{peak} = \frac{v_0 \cdot \sin(\theta)}{g} \)
Frequently Asked Questions (FAQ)

Q: Why does 45 degrees give the max range?
A: Mathematically, \(\sin(2\theta)\) is maximized when \(2\theta = 90^\circ\), meaning \(\theta = 45^\circ\). This assumes launch and landing heights are equal.

Q: How does air resistance affect the projectile?
A: Air resistance (drag) opposes the direction of motion. It reduces both the maximum height and the total range, and makes the trajectory asymmetrical (the descent is steeper than the ascent).
