Forces and Motion

INTRODUCTION

Issac Newton, a famous philosopher created the 3 laws that relate to forces and motions. What is a force? A force is a pull or push of an object. For example, if one were to push a box, they would be using force. An example of a force is gravity. Motion is the action or process of moving or being moved. Using the same example, the box would be in motion becuase it is being pushed. Some examples of motion are acceleration, speed, and velocity.

In our APS class, we covered topics that relate to forces and motion. Here are some that we covered: Issac Newtons 3 laws of Motion, Velocity, Acceleration
Scalar vs. Vector, Mass, Weight, Matter, Gravity, Friction, Inertia, Action-Reaction Force Pairs, and Magnetism

SCIENTIFIC MINDSET

What is Scientific Mindset?

A scientific mindset is how you better understand the world of Science. Each person's way of understanding science is different. My way of understanding science is by asking questions. When I do not understand something I ask questions. It also helps me to draw pictures. Pictures in science help me a lot becuase I can see everything and it helps me mentally see it.

Here are visual brainstorms that our class did on post it notes

MY PRE-UNIT CHALLENGE

My pre-unit challenge was seeing if mass affects speed. I did this by dropping a text book and a balloon. First, I measured 4 meters from the 5th grade balcony. Then, I asked one of my classmates to video the objects dropping using an app called vilmi. Vilmi is an app that records objects moving and in the app you can use markers to mark an important event. I dropped my balloon and my textbook down the balcony while being recored by vilmi. I then watch the video over again and concluded that mass does affect the speed of an object. The textbook reached the ground faster than the balloon.

NEWTON'S FIRST LAW

INERTIA

Inertia is the laziness of an object. It can also be called mass. The first law states that an object in rest will stay at rest unless an outside force acts upon the object. Or when an object is in motion, it will stay in motion unless an outside force acts upon it. For example, if a soccer ball was on a field and you kicked it, the ball would go flying across the field. At first the ball would be at a state of rest becuase it is resting on the field. It would stay in a state of rest, but then you, the outside force, applies force to the ball and it goes flying. After you kick the ball, the go flying through the air in a state of motion until gravity, pulls it back to Earth. Gravity is another outside force that pulls it down to Earth.
