Practice AP Physics 1 Dynamics: Force and Newton's Laws of Motion in the app →Newton's first law says a body at rest stays at rest unless acted on by:The property of a body to stay at rest or keep moving at constant velocity is called:A push or a pull is a vector quantity because it has magnitude and:Newton's second law says acceleration is directly proportional to net external force and:The SI unit of force is the newton, defined as the force needed to accelerate:Weight is a downward force, so weight equals mass multiplied by:An object sliding across a table slows down because of the net force of:On an air hockey table with the air turned on, the puck glides far without slowing because the surface is:Only which kind of force affects the motion of a system?Newton's third law states that if one object exerts a force on a second, the second exerts a force that is:A force exerted on an object is always due to:The diagram that shows only the external forces acting on one body is called a:A gravitational field g at an object's location exerts a force whose magnitude is:The weight of a 1.0 kilogram object on Earth is about:Weight is not an intrinsic property of an object because:When NASA speaks of weightlessness and microgravity, physics calls the same phenomenon:Objects falling toward Earth are never truly in free-fall in the real world because:How many basic forces are now taken to account for all known phenomena?
