Newton's First law

At the end of this lesson, you should be able to explain and apply Newton's First Law of Motion

Poll

Why is your body thrusted forward in a car when it brakes suddenly?

body was not firmly seated in car

your body continues to move at the same speed the car was moving at

the seat pushes you forward

Multiple Choice

What is Newton's First Law

F=ma

Every action has an equal and opposite reaction

An object at rest stays at rest, an object in motion stays in motion.

Friction

Because there is no unbalanced force to stop it (no matter in space).

Multiple Choice

Newton's 1st Law is also called the Law of ...

Friction

Inertia

Unbalanced forces

Newtons

Multiple Select

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

Multiple Choice

The law of inertia (Newton’s First Law) applies

to both moving and nonmoving objects

only to moving objects

only to objects that are not moving

Multiple Choice

What is the net force?

5 N

45 N to the left

5 N to the right

45 N to the right

0 N Right

0 N Left

30 N Left

30 N Right

Multiple Choice

8 N to the left , and 4 N to the right. Find the net force. Is this balanced?

12 N Right No

4 N Left No

12 N Right Yes

4 N Left Yes

Multiple Choice

Why is the net force 0 in the image?

Because the elephants are the same size

Because they are both pulling the same amount of force in opposite directions

Because they are elephants

Because they are pulling away from each other.
