1. What are the relationships between forces and motion? 
2. What are the variables that affect motion and force? 
3. How does Newton’s three laws describe the motion of a moving 
object? 
4. How does gravity impact objects?

1. Force is described as pressure that is applied. And motion is a certain movement, and it is usually the result of the force, or simply the energy given from the force. These to things work together on moving an object and both rely on each other so they can move an object. Without a force acting on the object the object would not be able to change its speed or direction. 
2.  There are many variables that affect motion and force and Friction is one of them. The force Friction is what slows down the motion of the object. Objects at rest have inertia, but when the object is in motion it has momentum and inertia. Momentum is the product of the mass and velocity of an object.Momentum is changed by how fast and object is moving and how much mass that object has. An example is a soccer ball being kicked. If the ball is kicked with a large force it goes faster, and the ball moves more quick. However, if the ball is kicked gently, then the ball moves slowly. The direction in which the ball moves is based on the direction of the foot when the ball is struct. 
3. The three laws describe the relationship between an object  and the forces acting upon it. The first laws says that an object either remains at rest or continues to move at a velocity unless acted upon by an external force. The second law is when an object is equal to the mass of that object multiplied by the acceleration of the object. 
4. One thing gravity affects is our weight for example, on the moon you would less because the moon has less gravitational force. Where as on earth we weigh more because it has more gravitational force.  

Newtons laws and mechanical motions

I learned a lot about Newtons laws: 

• I have learned that newtons first law of motion is also known as the law of inertia.
• Newtons first law says that an object is not moving, or is at rest, will stay at rest , and an object that is moving will keep moving in constant acceleration which means at the same speed and direction
• i have also learned that inertia is the property of anything that has mass.
• i have also learned that the equation that is used to solve second law problems is F=ma
• The greater the force that is applied, the greater the acceleration.
• The lesser the force that is applied, the lesser the acceleration 
• 
  

Proving newtons second law

Question: what is the relationship between Force, Mass, and acceleration ?

Materials Used: Car, Weights, Scale.

Hypothesis: They are all elements of an object. They all affect each other in an experiment.

Procedure: Step one: we started off with setting up the board flat. we put the 200g weight and pulled the car with the scale. We put down the results we got.

Step two: We then inclined the board and pulled the car up with three different weights. 20,100,200. WE wrote down the results and we also had the board inclined on the text book.

Step three: we then changed the incline again and put it up on a weighing scale. We changed the weights so we could get different results.

Step four: when we were done finishing that we had our graph all filled out.

Step Five: We then made a line graph and we had finished



Graph:


Height /  flat /  textbook /  scale / acceleration
200g    200N   .6            110           1
20g      .1N      .2            50           10
100g    .5N      .25          70            10



Conclusion: Our conclusion ended up being weird because our graph and measurements didn't make any since so we had to keep trying to correct it but it didn't come together. However i had fun doing the experiment and i am looking forward to having our next lab.
