- Q1What is the definition of Force?Law of Inertiaa push or a pull. Causes an object with a mass to change its velocity (speed or direction)A force that holds back the movement of a sliding object or the force that holds back the movement of two touching thingsMeasure of how fast something is moving30sEditDelete
- Q2Define Motiona measure of how much matter in an objecta change in positionA measurement of a change of an object’s velocity.A force which pulls two objects together.30sEditDelete
