Inertia

An objects desire to stay in the same motion.

• Momentum

• Intertia

• Magnitude

• Direction

Complete the excerpt of Newton's First Law of Motion "...and an object at rest will ________ until acted on by an unbalanced force."

• ...stay at rest...

• ...start an increasing motion...

• ...start a decreasing motion...

Which of these are GREAT example of inertia?

• a person flying through the windshield during a car wreck because they weren't wearing their seat belt

• a person staying in the vehicle and hitting the air bag during a car wreck because they are wearing a seat belt

• earth constantly traveling at the same speed in it's orbit

• a meteor traveling through space at a constant speed until it hits something

Inertia is Newton's _______ Law of Motion.

• First

• Second

• Third

Objects with MORE mass have...

• MORE inertia

• LESS inertia

• the SAME amount of intertia

Objects with more mass are..

• harder to speed up or slow down

• easier to speed up or slow down

Complete the excerpt of Newton's First Law of Motion

"An object in motion will ________ until it is acted on by an unbalanced force."

• ...stay in motion...

• ...stop its motion...

• ...increase its motion...

• ...decrease its motion...

What force is there on Earth that makes inertia hard to understand because our objects do not stay in motion forever?

• friction

• air resistance/drag

• gravity

Resistance of an object to a change in its motion.

• Mass

• Momentum

• Inertia

• Gravity
