Report Period 2 Preview

Hello! RP2 will be about forces and their interactions! We will be drawing heavily from our knowledge from RP1 on vectors.

Go Here for Calendar and Important Course Documents 

Essential Understandings:
Forces explain the interactions between objects which cause a change in motion in one or both of the interacting objects. Newton's laws of motion explain the effects of forces on an object's motion for almost all objects at the macroscopic level. Any discrepancies to these laws are most likely due to the neglect of another force.

A stable system is one in which the internal and external forces are such that any small change results in forces that return the system to its prior state. A system can be static (unmoving) but unstable, with any small change leading to forces that tend to increase the change. A system can be changing but have stable repeating cycles of change.

10/13 Angles and Stuff

I wanted to play Angry Birds with you because it's an amazing way of conceptualizing projectile motion, but it's blocked on the school network. Whatever - sic transit gloria mundi amirite?


Today we discussed the factors that contribute to a projectile's motion. We identified:
- Air Resistance - will slow objects down
- Initial Velocity - will change how far an object goes but not how long it takes to fall
- Gravity - will change how quickly the object accelerates (for example, acceleration due to gravity on the moon is - 2.16 m/s^2 as opposed to -9.81 m/s^2 on earth)
- Angle - What angle the object is thrown:

Graphic:


When we focused on angle, we wanted to know how high, far, and how long it would take for an object to travel if we changed the angle. This is what we will investigate tomorrow!

Physics - Week of 10/13-10/16

Hi All,

This week we are finishing up mini-unit 4 on projectile motion. Hopefully, we can finish by Thursday and begin reviewing for benchmarks the end of Thursday. Benchmarks are next week on Wednesday and Thursday. I hope everyone enjoyed their day off!


Tuesday: 

What factors affect the motion of a projectile? 

Wednesday: 

How does the angle of a projectile affect its motion?

Thursday: 

Solve projectile motion problems: maximum distance, flight time / Benchmark Overview

Friday: 

How can we apply what we learned throughout this unit? 
Focus: Distance, Displacement, Velocity, and Graphing 

Here are a few very helpful resources on projectile motion:
