Recalling the relationship between force and period of circular motion, the period, radius and mass of the satellite are related to the centripetal force pulling the satellite away from a straight ...

Yan explains what happens if one person lets go in term of Newton’s first law of motion. So, there must be a centripetal force pulling inwards on anything moving in a circle. For the cup of ...

Gravitational attraction provides the centripetal force needed to keep a planet in ... An object moving in a circular orbit at a constant speed has a changing velocity. This is because velocity ...
