Thinking Hard About Physics Before Calculating: An Example from Pendulum Physics
Zhiwei Chong
This paper aims to show how to guide students with a familiar example to extract as much physics as possible before jumping into mathematical calculation. The period for a physical…
A Close Examination on Inelastic Collision
Zhiwei Chong
This paper examines the details of an inelastic collision when a bullet shoots a block vertically upward from below. With the assumption of constant interaction force between them,…
A Qualitative Analysis to Simple Harmonic Motion
Zhiwei Chong
This paper proposes a qualitative analysis to the simple harmonic motion for students who are not mathematically well-prepared. It uses the variation in speed and acceleration to s…
Novel Approaches to Solve Simple Harmonic Motion
Zhiwei Chong, Yajun Wei
This paper presents two novel approaches to solve the classic simple harmonic motion. In one approach, the distance between the equilibrium position and the maximal displacement is…
