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 |
