Learning Outcomes:
Upon successful completion of this course students will be able to:
- Do dimensional analysis and unit conversions.
- Solve motion problems and draw motion graphs in constant acceleration, including free fall.
- Add, subtract, multiply vectors using different techniques such as graphic, component, and unit vector approaches.
- Solve two/three dimensional motions by separating them into one-dimensional motions including projectile motion.
- Apply Newton's laws of motion to kinematics and dynamics of different point mass systems by using proper free body diagrams.
- Calculate work of different forces including frictional force, gravitational force, and spring force using algebra and calculus.
- Calculate potential and kinetic energies of different conservative and non-conservative systems.
- Apply momentum and energy conservation rules to find velocities/directions of two (or more) colliding bodies.
- Calculate torque of forces and apply Newton's law for rotation to derive angular position, speed, acceleration, and equations of motion.
- Apply conservation of angular momentum to extended objects to determine the outcome of a rigid rotating system.
- Apply Newton's 2nd law for a spring force and derive the equation of harmonic oscillation, including simple pendulum.
- Set a wave equation and solve it to find frequency, wavelength, period, wave speed and their relationship.
