The strength of the force of gravity depends on ...
distance between the two objects
mass of the two objects
mass of objects and distance between them
When an object travels around another object in space, we call this
terminal velocity
projectile motion
orbit
rocket science
this occurs when only gravity is acting on an object
terminal velocity
free fall
projectile motion
air resistance
If a feather and a hammer are dropped at the same time which one will hit the ground first?
it can be one or the other depending on how fast they fall
hammer because it has more mass
feather because it has less mass
both will hit at the same time
