Answer Key and Explanations Explanation Motion krossvord po fizike 9 klass po ucheniku peryshkin 1 glava

: A physical quantity equal to the product of a body's mass and its velocity. Explains why objects stay at rest or keep

: The phenomenon where a body maintains its velocity when no external forces act upon it. Force 7

Conducted experiments on inclined planes to study free fall and inertia. Distinct from "path" because it has a specific direction.

: A vector quantity that is a measure of the interaction between bodies.

The author of the three laws of interaction studied in Chapter 1.
