A physics instructor needs to create instructional videos demonstrating Newton's laws of motion. Which tool should the instructor use to record, edit and share these videos with students?

Camtasia is the tool to record, edit and share instructional videos of Newton's laws of motion.

Flipgrid (A) is a short video-discussion platform, not a full editing tool.

Padlet (C) is an online collaborative board for posting content, not video editing.

Google Forms (D) creates surveys and quizzes, not videos.

Camtasia combines screen recording with editing to produce polished tutorials.

It suits screencasts and demonstrations that need trimming, captions and sharing.
