PS Module 3: Forces & Newton's Laws

force that opposes the motion of objects that move through the air

force that is directed toward the center of a curved or circular path

a region of space in which every point has a physical quantity, such as a force

a push or pull exerted on an object

describe the fall of an object on which only the force of gravity is acting

force that opposes motion between two touching surfaces

attractive force between two objects that depends on the masses of the objects and the distance between them

tendency of an object to resist a change in motion

states that if no external forces act on a group of objects, their total momentum does not change

sum of all the forces acting on an objects
