Edexcel IGCSE Physics: Double Science 复习笔记：8.1.4 Orbital Period

Calculating Orbital Period

 

  • When planets move around the Sun, or a moon moves around a planet, they orbit in circular motion
    • This means that in one orbit, a planet travels a distance equal to the circumference of a circle (the shape of the orbit)
    • This is equal to 2πr where r is the radius a circle

     

  • The relationship between speed, distance and time is:
