Acceleration

Detta klipp beskriver begreppet acceleration

Tyngdacceleration

Accelerationen, a, vid fritt fall (tyngdaccelerationen, g) beror av jordens dragningskraft. Denna varierar något på jordklotet beroende på vilken breddgrad man befinner sig.

Allmänt gäller:

a=g

på våra breddgrader är g equals 9 comma 82 bevelled m over s squared. Längre söderut är g lägre och norrut högre.

Om vi försummar luftmotstånd har alla fritt fallande föremål denna acceleration.
