newtons law questions

1. What are the relationships between forces and motion?
The relationships between forces and motion is the newtons laws. The newtons laws often involved an object in motion staying in motion. unless acted upon by an outside force. This shows how forces and motion have to intertwine  or else objects would just stay in endless motion. That is the relationships between forces and motion.



 2. What are the variables that affect motion and force?
 the variables that effect force and motion would be gravity. Gravity because it causes friction and thus is an outside force affecting the motion and force of the object. This of course would also count frtiction as a force of motion and thus is also an effecting variable. BOOM

3. How does Newton’s three laws describe the motion of a moving
object?
 That an object in motion should tend to stay in motion. That an object also in motion tends to stay in motion unless activated by an outside force. also that an object that is not in motion will stay still.

4. How does gravity impact objects?
 gravity causes friction within the objects and the force. this causes the object to slow down. This labels them as an outside force which makes the object stop, also gravity pushes down on an object.

lab report race car thingamabob

                           


at the start of the experiment we set up a board at an angle which allowed us to race the cars at a downhill angle. after we raced the car without the weights we added weights starting with a small weight, moving to a larger amount. After we reached the maximum weight we graphed the equation and we found that the friction increases with the amount of pressure and mass added on by the weights which caused the car to slowdown.  we then answered some questions and graphed the equation
