Newtons quiz


1. What are the relationships between forces and motion? 

The relationships between forces and motion is the potential energy that will be given. Force is the amount of pressure that is being given. The motion is the the movement being applied. An example is the the car. 

2. What are the variables that affect motion and force? 

The gravity is affecting the motion and the force. The speed is depending on weather if the gravity is being affected. 

3. How does Newton’s three laws describe the motion of a moving object? 

The first law is whatever is in motion stays in motion. The second law is it will only move if theres a net force or an unbalanced force. Newtons 3rd law is for every action so there will be an equal or opposite reaction. You have to put all 3 parts of the Newton's laws to explain this. 


4. How does gravity impact objects?


This can push something toward things. They might be going out but instead they will be going in. This happens to things if theres a different mass or acceleration.

Proving Newton's Second Law

Proving Newton’s Second Law


Question- What is the relationship between force, mass, and acceleration?





Materials used

·        … Car, weight, books, protracker, 2 spring scales, and a table

Hypothesis- I think that they will way pretty much the same.



Procedure-

11.       Collect Materials
22.       Set Up
33.       Make sure I had my journal and  pencil
44.       Make a graph in my journal
55.       Start our lab
66.       Pull weights up the ramp 9 times with  the spring scale
77.       Calculate  the acceleration
88.       Clean up materials
99.       Graph the data which means on 1 graph mass (x) and acceleration (y) and then on the 2nd graph angle (x) and Acceleration (y)  and it’s a line graph
110.   Answer the questions in my journal
111.   Put away my journal and pencil
                       


Results

 

Data Table



Graphs of Data



Conclusion and Analysis- They were the did the same thing with the graphs because ours went in a straight line.

 1. What happened when you kept the mass the same and changed the angle?
 It stayed the same and it didn't change.

2. What happened when you kept the angle the same and changed the mass?
It did the same thing as the whole time.

3. What was the relationship did u notice?
 My graphs went in a straight line.
