Question
Unit 5- Force & Motion-Newton's Laws of Motion: SampleWork Assignment
Directions:
For this assignment, you will show that you understand Newton's Three Laws of Motion. Answer the questions below and use examples from everyday life. Answers must be in complete sentences.
Step 1: Choose a situation from everyday life.
1. Pick an example where you see forces in action.
Examples might be riding a bike, playing basketball, or pushing a toy car.
Where does this situation happen?
(For example: At home, at school, outside, etc.)
What are the forces acting on the object?
(For example: gravity pulling down, pushing the car, etc.)
Step 2: Explain Newton’s Three Laws in your example.
Newton’s First Law (The Law of Inertia):
What happens when the object is not moving or when you stop moving it?
Example: When a soccer ball is kicked, it keeps moving until something stops it.
Newton’s Second Law (Force = Mass × Acceleration):
If you push harder, what happens to the object? Does it speed up more?
Example: If you push a toy car lightly, it moves slow. If you push harder, it moves faster.
Newton’s Third Law (For every action, there is an equal and opposite reaction):
What happens when you push something? What does the object do to you in return?
Example: When you jump off a swing, the swing moves back
Step 3: Reflection
Why is it important to understand Newton's laws?
Write a paragraph and explain why learning about how things move is helpful.
(For example: It helps us understand why cars speed up, why things fall, or why it’s hard to stop a big object.)

### Step 1: Choose a situation from everyday life
For my example, I will use riding a bicycle, which commonly occurs in various settings, such as parks, streets, or bike paths. In this scenario, the forces acting on the bicycle include gravity pulling it down toward the ground, friction between the tires and the ground that allows it to move forward or come to a stop, and the force of the cyclist's legs pedaling to propel the bike forward.
### Step 2: Explain Newton’s Three Laws in your example
**Newton’s First Law (The Law of Inertia):** When the bicycle is at rest, it will stay stationary until I push the pedals to move it. Conversely, when riding the bike, if I suddenly stop pedaling, the bike will gradually slow down and eventually come to a stop due to friction and gravity acting upon it. This example illustrates that objects at rest stay at rest, and objects in motion continue to move unless acted upon by an external force.
**Newton’s Second Law (Force = Mass × Acceleration):** If I apply more force by pedaling harder, the bicycle will accelerate and move faster. For instance, if I gently push on the pedals, the bike moves slowly, but if I push down with greater force, it speeds up significantly. This law demonstrates that an increase in force results in greater acceleration of the object, assuming the mass remains constant.
**Newton’s Third Law (For every action, there is an equal and opposite reaction):** When I push down on the pedals of the bicycle, my feet exert a force on the pedals, and the pedals in turn exert an equal and opposite force back on my feet. This interaction allows me to transfer energy efficiently, enabling the bicycle to move forward. This law emphasizes that all forces come in pairs; when I act upon one object (the bike), the bike responds equally.
### Step 3: Reflection
Understanding Newton's laws is crucial because they provide the foundation for comprehending how and why objects move the way they do in our daily lives. By learning these principles, we gain insight into various physical phenomena, such as why it takes more effort to stop a heavy truck compared to a small bicycle, or why a soccer ball continues to roll until friction or another force brings it to a halt. This knowledge helps us apply force effectively in sports, engineering, transportation, and even safety measures. Overall, grasping Newton's laws enhances our ability to predict and manipulate motion, ultimately improving our interactions with the physical world.
