It gives the foundation for understanding the movements of object (position, velocity and acceleration) in space and the main interactions (forces, energies) between objects/systems involved in these movements. Pre-requisites: Mathematics, 31A, 31B, 32A. http://physics-1-series.physics.ucla.edu/ http://catalog.registrar.ucla.edu/ucla-catalog20-21-1202.html Course topics: • Units, vectors, kinematics • 1D, 2D, 3D motion • Newton’s Laws and their application • Work and kinetic energy

UCLA – Physics Department – Spring 2022 Page 2 of 4 • Potential energy and energy conservation • Momentum, impulse, and collisions • Rotation of rigid bodies • Dynamics of rotational motion, equilibrium • Gravitation GRADING, EXAMS & POLICIES _____________________________________________________________________________________ Grading Attendance to Discussion 2% (managed by TA) Discussion session exercises 8% (graded by TA) Homeworks: 10% (graded on completion – Kudu) Pre-lecture exercises 10% (graded on completion – Kudu) Midterm 1: 20% Midterm 2: 20 % Final Exam 30 % Lab activities (extra credit) up to 5% TOTAL: 105% Homeworks and after-classes exercises are managed online on Kudu website. Homeworks are assigned a week ahead of time. There will be two midterms and a final exam in-person. There will be no automatic makeup exams. Missed exams will be handled by the instructor on a case-by-case basis. Your worst homework score is automatically dropped at the end of the course and not considered in the final grade. The final grade will be based on the weighted average with a “safety net”. This way, a student can never get a lower grade than that given by a “curve”, but it is possible to get a higher grade based on absolute performance: A+ > 98 % of the total score or top 2% of class (whichever gives higher grade) A 94-98% of total score or 3-10% of class (whichever gives higher grade) A- 90-93% of total score or 11-30% of class (whichever gives higher grade) B+ 86-89% of total score or 31-40% of class (whichever gives higher grade) B 83-85% of total score or 41-50% of class (whichever gives higher grade) B- 80-82% of total score or 51-60% of class (whichever gives higher grade) C+ 76-79% of total score or 61-70% of class (whichever gives higher grade) C 70-75% of total score or 71-80% of class (whichever gives higher grade) C- 66-69% of total score or 81-90% of class (whichever gives higher grade) D+ 60-65% of total score or 91-93% of class (whichever gives higher grade) D 56-59% of total score or 93-95% of class (whichever gives higher grade) D- 50-55% of total score or 95-98% of class (whichever gives higher grade) F Otherwise There will be a self-pace lab activity using the sensors of your smartphone once every week. Please download Phyphox applet. The labs represents an extra credit up to 5% in top of your overall grade.
