Dynamics

The Big Ideas included in the Ontario Curriculum about Dynamics are:
  • Forces affect motion in predictable and quantifiable ways. 
  • Forces acting on an object will determine the motion of that object. 
  • Many technologies that utilize the principles of dynamics have societal and environmental implications.

By the end of this section, students will
  • analyse technological devices that apply the principles of the dynamics of motion, and assess the technologies’ social and environmental impact;
  • investigate, in qualitative and quantitative terms, forces involved in uniform circular motion and motion in a plane, and solve related problems;
  • demonstrate an understanding of the forces involved in uniform circular motion and motion in a plane.

Current Topic

We are not currently studying Dynamics.

Schedule

It is expected you will have read the relevant sections of the text book prior to class. Dynamics is covered in chapters 1, 2 and 3.

Another cool video is the following by MIT of the projectile and target problem (similar to question 8 on page 43). Check it out if you get a chance.
To get a sense of mechanical advantage provided by a pulley system, check out this Tug of War YouTube video.
One of the better videos I have seen produced using an accelerometer for circular motion.
