the sun (our star) , 8 planets (mercury , venus , earth , mars , jupiter , saturn , uranus , neptune)
the planets natural satellites ( ie the moon)
dwarf planets ,
comets and asteroids
my very educated mother just served us nachos
explain how the force of gravity acting on a satellite affects its speed and velocity
the force can alter its velocity since the direction is constantly changing , it cant affect its speed since there is no force component in the direction of motion
explain why , for a stable orbit , the radius of orbit must change if speed changes
at higher speeds =
the object requires higher centripetal force
for a greater centripetal force,the gravitational force must increase
