### Title

Units and Significant Figures

### Learning Outcome

Convert quantities from one set of units to another and use a reasonable number of significant digits when expressing answers.

### Title

Motion of a Particle

### Learning Outcome

Interpret and draw motion diagrams including "blinking light'&nbsp;diagrams, x(t), v(t), a(t), and y(x) plots. Understand what time derivatives mean and how to&nbsp;estimate time derivatives from the information in these diagrams.&nbsp;Compute a particle's classical translational motion in one or two dimensions, including circular motion, both in Cartesian coordinates and in polar coordinates.

### Title

Energy and Momentum

### Learning Outcome

Use the ideas of energy, work, power, linear momentum, impulse, and&nbsp;angular momentum to arrive at conclusions about the motion of a&nbsp;system, including systems in which collisions occur.

### Title

Newton's Second Law

### Learning Outcome

&nbsp; Use Newton's Second Law to calculate the motion of objects,&nbsp;both in translation and rotation, and also&nbsp;those in simple harmonic motion, as well as the forces and&nbsp;torques acting on systems in equilibrium. Also use Newton's inverse-square law of gravity to calculate how objects move.

### Title

Scientific Process

### Learning Outcome

Demonstrate an understanding of the basic scientific principles that undergird the scientific process, including the strengths and weaknesses of this process.
