PHYS 2APhysics—Mechanics

4 units · PHYS · UC San Diego

A calculus-based science-engineering general physics course covering vectors, motion in one and two dimensions, Newton’s first and second laws, work and energy, conservation of energy, linear momentum, collisions, rotational kinematics, rotational dynamics, equilibrium of rigid bodies, oscillations, gravitation. Students continuing to PHYS 2B/4B will also need MATH 20B. Students will not receive credit for both PHYS 2A and PHYS 2AR.
