Forces CPD videos (age 14-16)

DOMAINS CPD for 14-16 16-19 IOP RESOURCES

Where possible we have tried to avoid exam-board specific terminology so that you can adapt the examples used to the needs of your students.

Videos created by the DOMAINS CPD programme, presented and developed by IOP coaches, on the topic of Forces for students aged 14-16.

Newton 3 (YouTube link)

Presenter: Daisy Fox

Length: 16 minutes

Starting the count down through Newton’s laws of motion we start with unpicking a typical exam question about the forces acting on a rocket and how students often get confused about interaction pairs. Daisy’s video builds on the ideas presented in the Force Arrows session around language and carefully positioning arrows to reinforce understanding.

Newton 2 (and vectors)

Presenter: Kath Myers

Length: 14 minutes

Kath brings us back down to Earth as we move to Newton 2, there’s an animated variation on ticker tape as we examine how unbalanced forces affect motion. Vectors are introduced to describe forces and help with adding two forces to find the resultant. Finally, we look at the effect of the resultant force on acceleration.

Newton 1

 

Presenter: Sue Woolhouse

Length: 8 minutes

In the last of the Newton 3,2,1 collection Sue Woolhouse presents the special case of Newton 2, where the resultant force happens to be zero. Many students have difficulty understanding that an object can move with constant velocity even when there isn’t a force acting in the direction of motion. This idea was recorded well over 2,000 years ago in China, long before Newton's laws. The session ends with curly arrows to model a sky diver’s descent and explain terminal velocity.
