Momentum and impulse problems in one dimension are presented and solved. All these practice problems are for your homework and/or the AP Physics 1 exam.

Some problems about air-filled parallel-plate capacitance are presented and solved. These questions are for high school and college students. Each solution is designed so that it be a self-tutorial on this subject.

The significant figures calculator undertakes calculations with significant figures and works out how many significant figures (sig figs), i.e., digits, a number holds

A 5-kg object performs a circular motion with a radius of 18 cm at a constant speed of 6 m/s. Find the magnitude and direction of the centripetal acceleration of the object.

Using a position vs. time graph, displacement, average speed, and velocity, and acceleration of motion are found. We find these kinematics quantities with plenty of solved exam problems.

Velocity-time graphs give us acceleration using slopes, displacements by areas, turning points, and type of motion. We will address these topics with plenty of solved problems.
