Six Ideas That Shaped Physics C2
| Question | Answer |
|---|---|
| A physical relationship between two objects that allows them to change each others motion | Interaction |
| an interaction between two macroscopic objects arising from direct physical contact | contact (interaction) |
| an interaction involving gravitational or electromagnetism | long-range (interaction) |
| manifestation of interaction | force |
| motion of an isolated object does not change | Newton's first law |
| distance/time | speed v |
| an intrisnic characteristic of an object expressing resistance to changes in motion | mass |
| a law of physics asserting that an interaction between two objects conserves their total momentum | conservation of momemtum |
| the gravitational fore acting on an object | weight |
