Experiment Guide — What changes do

Simple Pendulum

  • String length (L): Longer → slower oscillations (period ↑).
  • Initial angle: Larger angle → bigger arc; small angles ≈ harmonic motion.
  • Gravity (g): Higher g → faster oscillations (period ↓).
  • Damping: Larger → amplitude dies out sooner.

Increasing the pendulum length will…

Projectile Motion

  • Initial speed: Higher → greater height and range.
  • Launch angle: ~45° maximizes range (no air drag).
  • Gravity (g): Higher → lower apex, shorter flight.
  • Restitution: Bouncier ground → higher rebounds.

Real-life examples

Test yourself

Ignoring air drag, the launch angle for maximum range is about…

Inclined Plane

  • Plane angle: Steeper → stronger component along the slope.
  • Friction (μ): Higher μ → more resistance; can keep block at rest.
  • Gravity (g): Larger g → larger normal and friction forces.

Real-life examples

Test yourself

If μ is large enough and the slope is small, the block will…

Elastic Collision (1D)

  • Masses (m₁, m₂): Change how momentum is shared.
  • Initial velocities: Direction and speed set outcomes.
  • Wall restitution: 1.0 = perfectly elastic bounce.
