Motion Test Exam Questions And Answers Verified 100% Correct

Motion Test Exam Questions And Answers Verified 100% Correct SPEED - ANSWER a rate of motion that depends on the distance an object travels over a period of time SPEED FORMULA - ANSWER Speed = distance / time VELOCITY - ANSWER a term used to describe an object's speed AND direction. ACCELERATION - ANSWER the rate at which velocity changes INERTIA - ANSWER the tendency of an object to resist a change in motion. Newton's 1st Law of Motion - ANSWER An object at rest tends to stay at rest and an object in motion remains in motion unless acted on by an unbalanced force. Newton's 2nd Law of Motion - ANSWER The acceleration of an object depends on the mass of the object and the force applied. A math equation that represents this law is: force = mass x acceleration (F=m x a) Newton's 3rd Law of Motion - ANSWER Every action has an equal and opposite reaction. AIR RESISTANCE - ANSWER the friction that opposes the motion of falling objects and moving objects, when air hits the surface of an object. VECTOR - ANSWER a quantity that shows both magnitude (amount) and direction. FORCE - ANSWER a push or pull exerted by one object on another. UNBALANCED FORCE - ANSWER the forces acting on an object when the net force is not zero. BALANCED FORCE - ANSWER forces that produce a net force equal to zero. NEWTON - ANSWER a measurement for force (N) MOTION - ANSWER an object's change in position over time DISTANCE - ANSWER how far an object travels FRICTION - ANSWER a force that works against motion, caused by tiny bumps and ridges in surfaces.
