## 1. Outline

### 1.1. Linear Motion

1.1.1. Learned how position and displacement differ.

1.1.1.1. Position is the location and a specific time whereas displacement undergoes motion and describes the total distance the object traveled.

1.1.2. Learned the difference of speed which is a scaler and velocity which is a vector.

1.1.2.1. Both have magnitude but velocity also includes direction.

1.1.3. Learned how to visually depict a motion diagram along with position versus time graph.

1.1.3.1. Continued on at a later day to draw the relationship between velocity and time along with acceleration and time.

1.1.4. Evolved from P1 which was not linear motion to P2 where we built a different launcher more sling shot style in order to aim at a target and create linear motion.

### 1.2. Non-linear Motion

1.2.1. Looked at with P1 where the motion of the marshmallow was not linear and more so circular motion.

1.2.2. Also for P3 motion was

### 1.3. Forces and Momentum

1.3.1. Began to look into force when we created out marshmallow launchers and force was what allowed our marshmallows to be launched its total distance.

1.3.1.1. Force also came into play when talking about Newton's 3rd law: when force is applied by someone or something, then an equal force has to be applied back to that person or thing.

1.3.1.1.1. Newton's law was discussed through P1 and also P3 when we choose Diving as our topic and the divers downward force on the board became important in order to apply Newtons law and gain maximum force from the board to create momentum in the y-axis (upward direction) to complete the dive.

### 1.4. Work, Energy Storage and Transfer

1.4.1. Beginning to look into energy for P2.

1.4.1.1. For Project two energy was transferred from the sling into the marshmallow, which then created kinetic motion. Motion from marshmallow was then transferred into the target which stopped the motion of the marshmallow.

1.4.2. Three ways to get energy in and out of system: Working, heating, and radiating.

1.4.3. Energy stored as spring energy, spring energy is then transferred into kinetic motion (energy stored in somethings motion).

1.4.4. Energy does not get destroyed, but instead transferred into the system stored in the gravitational environment.

### 1.5. Properties of Matter

1.5.1. Looking into extensive properties of matter: mass, weight, volume and length these variables became vital for some of the equations.

1.5.1.1. Ex. Force=mass*acceleration

1.5.1.2. Acceleration, force, velocity, range, etc are dependent upon a subject's mass, weight, volume, and length.

## 2. Competencies

### 2.1. Effectively communicate qualitative and quantitative information orally and in writing.

2.1.1. Commentary on others weekly neat videos along with emailing other classmates to discuss or compare answers on specified activities.

2.1.2. Effective communication through phone, email, and in person was what allowed me to complete my group projects, without effective communication the whole project will fail.

### 2.2. Explain the application of fundamental physical principles to various physical phenomena.

2.2.1. Through the neat videos that we upload weekly we are able to see how simple things that we see in everyday life can be related to physics.

2.2.1.1. The neat videos I uploaded include soccer, diving, and the trampoline which through physics we can explain how motion occurs and makes the movements possible through velocity, force, acceleration, time, and several other factors.

### 2.3. Apply appropriate problem-solving techniques to practical and meaningful problems using graphical, mathematical, and written modeling tools.

2.3.1. Filmed different variations of motion such as walking, running, and launching a marshmallow that was uploaded into Loggerpro which allowed us to analyze the motion along with graph velocity, position, and acceleration in accordance with time.

### 2.4. Work effectively in collaborative groups.

2.4.1. Worked on project one with Brianna and Leo to create a Marshmallow Launcher and once created we put together a tech glog explaining the physics of it.

2.4.1.1. Learned the hard way through P3 that not all group members are reliable so by effective communication with the remaining of my group we were able to work around the weakest link to finish the needed work for the project.
