force, push or pull on matter that enables that matter to CHANGE motion and interact; transfer and transform energy, net force, the sum of all the forces acting on an object, unbalanced forces, change the motion of an object; net force ≠0, balanced forces, do not change the motion of an object; net force =0, acceleration, ANY change in motion; can be in direction or speed, magnitude, the quantity or amount, Newton’s First Law/Law of Inertia, objects will remain at rest OR in constant motion UNLESS acted on by an unbalanced force, linear motion, the motion of an object traveling in a straight line, direction, the path of movement, speed, the distance an object travels divided by the time it takes to travel that distance, displacement, the object's overall change in position, from a starting point to an ending point, constant speed, when an object does not increase or decrease its speed, average speed, calculated by dividing the total distance traveled by the total time of travel; s = d/t, velocity, Speed + direction
