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
