Physics-Motion G9

Master physics motion basics! Grade 9 worksheet on reference points, displacement, and quantities.

Write your full name and class section A point against which direction (motion) is measured. scalar quantity reference point displacement The distance an object travels plus the direction from the starting point. reference point displacement acceleration A physical measurement that contains both magnitude and directional information. vector quantity scalar quantity displacement A physical measurement that contains only magnitude (number) and does not contain directional information. vector quantity scalar quantity acceleration All motion is distance displacement relative To accurately describe motion you need a frame of reference calculator distance 2 or more displacements can be combined by what method? graphing the slope using vector addition calculating the acceleration If an object is in motion, its position is changing stationary magnitude The science of _ is the branch of physics that deals with analyzing and understanding objects in motion. physics chemistry mechanics Distance is the _ of a path between 2 points. magnitude length displacement
