Newton’s Laws Demonstration Put Your Name
2
Open the simulation called Forces 1D Learn where the controls are to change objects, add/remove friction Learn where the controls are to change the friction coefficient Screenshot Add / remove friction buttons Screenshot Add / remove friction buttons Screenshot Where you would change objects Screenshot Where you would change objects Screenshot Where you would change friction coefficient Screenshot Where you would change friction coefficient CLICK ME FOR GAME!! 3 pts
3
– Crate – Original position – 0 – Graph Acceleration (and Force) – No Friction – Applied Forces Push the crate with any force so it starts to move to the other end…. Use your playback and pause button to find your HIGHEST force and acceleration it took to hit that force… type that data into the next slide.
4
Force= 620 N Mass= Crate(300kg) Acceleration= A=F/M=2.1 Graphed Acceleration= 2.1 YAY!!!!! Measure at peaks!!!!!!! Playback
5
Is the ratio of the force to the acceleration constant? If so, what does this tell you about the relationship between Force and Acceleration? ObjectMass of Object (kg) Force it took to move it (Newtons) Playback and stop when moving line gets to force peak Calculated acceleration A=Force/Mass Graphed Acceleration: Playback and stop when moving line gets to acceleration peak 25 pts
6
Add Friction, check the controls, and set the value to 0.2 for static and kinetic friction, Does friction help motion or oppose motion (acceleration)? ObjectMass of Object (kg) Applied Force (Newtons) Playback and stop when moving line gets to force peak Friction Force (N) Calculated acceleration A= F/M 16 pts

Newton’s Second Law in Space Reading: Read left side of page 1.What is the formula for Newton’s second law? 2.What is the acceleration of gravity on the planet Earth? 1.How fast will an object be falling if falls for three seconds Reading: Read left side of page 1.What is the formula for Newton’s second law? 2.What is the acceleration of gravity on the planet Earth? 1.How fast will an object be falling if falls for three seconds CLICK ME FOR GAME!! 3 pts
8
Make your game look like this and type in the data on the next slide! Then do the rest on your own

10
Conclusion 1. How did mass of objects effect which objects hit the ground first on Earth? 2. How did the size of the planet effect how much acceleration the objects had? 3. Which planet had the greatest effect on objects 3 pts
