Gravity and Motion

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

NGSS.MS-ESS1-2

NGSS.MS-PS2-4

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
