Thank you. 

Project Check in

How does your project show Newton's Third Law of motion? Every action has an equal an opposite reaction.

How does your project demonstrate Newton's first law?

Check in Collision Project

Please answer the following four sentences to check in on your progress for the Newton's Law Investigation. 

1. What is your hypothesis for your Newton's Laws project? 
2. Do you predict that your collision will be elastic or inelastic?
3. What do you estimate the mass of each of your objects to be? 
4. Which units will you use to show the speed of your object? 

What objects are you using

This week you are creating an investigation about Newton's Laws by creating a collision between two objects. 

1. What are the two objects that you decided to collide ? 
2. Which object will be still which will be moving?
3. How far apart will your objects be? 
4. How will you make a record of your collision? 

What type of a collision is it?

What is the difference between elastic and inelastic collisions? Please give an example of each. 

Bungee Jump

     Aedin is planning on building a bungee jump tower in his backyard. He wants a ride that last for five seconds. The town says he may not build a tower more than 50 meters tall. Avery says the tower would need to more than 50 meters tall to get a five second ride. Macey disagrees saying the rate of fall is just 9.8 meters per second squared due to gravity.  Therefore the tower would only need to be 49 meters tall. Who is correct Avery or Macey? Would Aedin be allowed to build his five second bungee jump?
