Newton’s Laws

1. Newton’s Laws Class Notes Patrick Kocsis McMillan Magnet Middle School Omaha Public Schools

2. Newton’s First Law • An object at rest remains at rest and an object in motion remains in motion (at a constant speed and in a straight line) unless acted on by an unbalanced force. • How does this animation prove Newton’s 1st Law?

3. Newton’s First Law • Write three examples of the 1st law: • Draw a diagram of Newton’s 1st law:

4. Newton’s Second Law • The acceleration of an object depends on the mass of the object and the amount of force applied. • Equation • Force=Mass x Acceleration (F=M x A)

5. Newton’s Second Law • How do these animations prove Newton’s Second Law?

6. Newton’s Second Law • Write two examples of the 2nd law • Create a diagram showing the 2nd law

7. Newton’s Third Law • For every force there is an equal and opposite force. • How do these animations prove Newton’s Third Law?

8. Newton’s Third Law • Write three examples of the 3rd law: • Draw a diagram to demonstrate the 3rd law:

9. Putting the Laws Together • Boat Lab • Students will design and build boats that will compete in the “Monarch Grand Prix” to win a grand prize of 100 Grand. • Students will complete a computer simulation of the boat lab that applies Newton’s Laws to the task. • Students will design and create balloon-powered boats. • Students will work within a budget. • Students will complete a formal lab write-up utilizing the scientific method.

14. Simulation Suggestion 1 • Mass • Create 3 different sized ‘boats’ • The highest mass moves slowest, the lowest mass moves fastest across the track. 90g S l o w M o v e m e n t M e d i u m M o v e m e n t 60g 30g F a s t M o v e m e n t = Boat = Track

15. Simulation Suggestion 2 • Force • Use 3 different sized balloons but same sized boat • The lowest amount of force moves slowest, the highest amount of mass moves fastest across the track. S l o w M o v e m e n t M e d i u m M o v e m e n t F a s t M o v e m e n t = Boat = Track = Balloon

16. Simulation Suggestion 3 • Boat design • Create 3 same massed boats, but change hull design • The blunt front moves slowest, the sleekest front moves fastest across the track. S l o w M o v e m e n t M e d i u m M o v e m e n t F a s t M o v e m e n t = Boat = Track = Balloon

17. Simulation Suggestion 4 • Mass, Force, and Design • Students can create their own boats, using the three variables to check their design for efficiency Mass Choices Force Choices Design Choices (Boat) (Balloon) (Hull) 90g 60g 30g M o v e m e n t T i m e d Student Boat = Track
