NGSS.MS-PS2-2

The tendency of an object to resist a change in motion.

• gravity

• friction

• air resistance

• inertia

Resistance to motion when two objects are in contact with one another.

• inertia

• friction

• air resistance

• gravity

An object will move at a constant velocity unless an unbalanced force acts upon it.

• Terminal Velocity

• Gravity

• Inertia

• Newton's 1st law

Resistance an object feels when travelling through the air.

• Force

• Gravity

• Air Resistance

• Friction

The attraction two objects have on one another.

• friction

• air resistance

• weight

• gravity
