 Newton's First Law: Law of Inertia Objects will remain in motion, in a straight line and at a constant speed unless acted upon by a force Net force any influence that may change the state of motion of objectsan unbalanced force Newton's 2nd Law: Law of forces and accelrations if ourside net forces act upon objects, then objects are accelerated.when this happens objects are accelerated in the direction of the net forces. inversely proportional to objects inertia quantitive measurement of inertia objects mass mass total amount of material in an object acceleration force/mass force=mass * acceleration weight how gravity affects or accelerates mass. scalar quantity remains the same no matter where you travel in the universeMASS vector quantity changes depending on where you are.weight inertia the tendency of the object at rest to remain at rest. and of a body in motion in a straight line at a constant speed. Force push or pull anything that can cause a body to change velocity. velocity a physical quantity that indicates both the spped of a body and the direction in which it is moving. Newston's 3rd Law: law of active-reactive forces if an ovject exerts a net force upon another object (action), then the second object exerts a second net force upon the first object (reaction)the two forces are equal in magnitude but opposite in direction.f1=f2 The relationship between acceleration and forces if an outside net force acts upon an object, the object is accelerated in the direction of the net force light Authorvpenaloza23 ID11040 Card SetAstro test 2 DescriptionAstro Test 2 Updated2010-03-18T01:15:36Z Show Answers
