NGSS.MS-PS2-4

tendency of an object to resist any change in its motion

• inertia

• gravity

• free fall

• terminal velocity

states that if no external force acts on a group of objects, their total momentum does not change

• law of conservation of momentum

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

states that an object moving at a constant velocity keeps moving at that velocity unless an unbalanced force acts on it

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Law of Conservation of Momentum

the maximum speed an object will reach when falling through a substance, such as air

• terminal velocity

• air resistance

• weight

• centripetal force

gravitational force exerted on an object

• weight

• free fall

• gravity

• terminal velocity
