AP Physics C First Semester Review of EVERYTHING I learned KINEMATICS: The general relationship between position, velocity, and acceleration: o I can analyze x vs. t, v vs. t, and a vs. t graphs o Given one equation (x, v or a), I can find the other 3. I know 4 main kinematics equations:

Students should know how to deal with situations in which acceleration is a function of velocity and time and write an appropriate differential equation and solve it for v(t), for example: A vector is: o The rules for adding vectors: o I know how to find a resultant vector: I know how to use my 4 kinematics equations to solve problems in 2 dimensions: o My main “projectile” formulas: o Velocity in x-direction vs. Velocity in y-direction: o Basic picture of a projectile with velocity and acceleration vectors:
Given functions of x(t) and y(t), I can determine the components, magnitude and direction of the particle’s velocity and acceleration. DYNAMICS/NEWTON’S LAWS Newton’s Three Laws: o 1 st o 2 nd o 3 rd Net force means: If there is NO NET FORCE on an object, then the object is doing 1 of 2 things: o The object is o Or the object is I can draw a well-labeled for body diagram, for example: I know the steps for solving… o Hanging stop light questions:

o Pulley questions: o Pulley on Table questions: o Pulley on Ramp questions:
When I sum my forces, I know that I can set them equal to 1 of 2 things: o = o = Friction is: o 2 types of friction: o What the coefficient of friction means: o Formula for Frictional force: o I can figure out when an object will start to slip, for example: Terminal Velocity is: o I can calculate terminal velocity, for example: o I can describe with graphs or words the acceleration, velocity and displacement of a particle reaching terminal velocity after falling or being projected, for example:

o I can use Newton’s 2 nd Law to write a differential equation for the velocity of the object as a function of time: o

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
