Newton's First Law:

Newton's First Law

I've heard of Isaac Newton.

• Yes

• No

• That type of cookie

3. Isaac Newton is familiar to me and I may know some of his Laws of Motion..

• Yes

• No

Law #1:  

An object at rest tends to remain at rest.

Law #1:  (continues)

An object in motion tends to stay in motion...

Law con

at a constant velocity and in a straight line...

Newton's 1st Law

(Law of Inertia)

An object at rest tends to remain at rest. An object in motion tends to remain in motion at a constant velocity and in a straight line until it is acted upon by an unbalanced force.

Newton's 2nd Law

F=ma

Multiple Choice

What is a Force?

• Something a Jedi uses

• Force is inertia.

• Force is a push or a pull.

Engineers at SpaceX must determine the net force needed for its Starship rocket to achieve an acceleration of 70 m/s² . If the mass of the rocket is 5,000,000 kg, how much net force must the rocket develop?

Please write any ideas you may have on how to solve this. If you don't know how to solve, that's ok....write what you do know.

Consider starting here: What is the mass of the Starship Rocket?

Newton's 3rd Law

Action/Reaction

For every action force there is an equal and opposite action force.

Example

paddle moving back =

boat moving forward

What is a question you still have about Newton's 3 Laws?

Open Ended

Give an example of one of Newton's 3 laws and how it relates to YOUR life or what you are interested in.

Module 3-1: Weight and Friction

• Mass and Weight are NOT the same! Weight depends on Mass.

• Weight is the downward force of gravity pulling on an object.

• Friction is a contact force that resists motion. ​It depends on the surfaces' material and the force pushing them together.

• The coefficient of friction ​determines how "sticky" a surface is.

• Higher = "Grippy" & Lower = "Slippy"

Learning objective

We Will: define and demonstrate Newton’s Three Laws of Motion.

I Will: differentiate between newtons three laws of motion based on the scenario given and determine how a scenario applies to more than one law.
