Student misconceptions on forces and motion

Today I continue to put down the student misconceptions on forces and motion as reported from physics education research. Every physics teacher will encounter the misconceptions every time when they teach force and motion. It is inevitable because of the “mismatch” of what was taught with the daily life experience. However, there is actually noContinue reading “Student misconceptions on forces and motion”

“On” and “by”

In describing forces, one needs to take note of the “on” and “by”. We need to mention the object the force exerts on and the agent that exerts the force. For example, the weight of the block is the gravitational force by the Earth on the block. Note: If you prefer gravitational force on the block by the Earth, that is fine too!Continue reading ““On” and “by””
