  • Scope of Supply

Principle

The fall times t are measured for different heights of fall h. h is represented as the function of t or t², so the distance-time law of the free fall results as h = 1/2 · g · t². Then the measured values are taken to determine the acceleration due to gravity g.

Benefits

  • Gravitation scrutinized
  • Find out how the velocity of a falling object increases
  • Didactical demonstration of the falling distances
  • Visualise the squared distance-time law
  • Steady set-up
  • All crucial parts directly engineered for this experiment

Tasks

Determination of

  1. distance time law for the free fall,
  2. velocity-time law for the free fall,
  3. precise measurement of the acceleration due to gravity for the free fall.

What you can learn about

  • Linear motion due to constant acceleration
  • Laws governing falling bodies
  • Acceleration due to gravity
