The Physics portion of Science 10 has two main parts: MOTION and NUCLEAR PHYSICS
MOTION: Chapters 8 and 9
This section studies motion with constant velocity and motion with constant acceleration. There is discussion of the difference between SCALARS like distance and speed and VECTORS like displacement and velocity
The unit begins with a review of science 9 motion with constant velocity and then extends to motion with constant acceleration. (8.1)
Key ideas are the difference between positive and negative acceleration. Extensive discussion is done to dispel the misconception that negative acceleration means slowing down while positive acceleration means speeding up. Formulas are given to relate velocity acceleration displacement and time. (9.1 and 9.2)
Finally we look at graphs of motion for both constant velocity and for constant acceleration. (8.2)
NUCLEAR PHYSICS: Chapter 7
In this section we look at ISOTOPES, RADIOACTIVITY and NUCLEAR REACTIONS.
We already discussed isotopes when we looked at atomic theory in chemistry. Now we focus on the role of neutrons and why some elements are unstable. We study the three main types of radioactive decay: ALPHA, BETA and GAMMA (7.1)
