A change in speed or direction, acceleration, velocity, balanced forces, inertia, Velocity is speed and..., acceleration, distance, time, direction, Balanced forces , never change motion, always change motion, have a net force ǂ 0, always go the same direction, Unbalanced forces, have a net force = 0, always causes acceleration, never change an object's motion, cause an object to maintain a constant speed, Speed, =distance/time, =mass x acceleration, =time/distance, rate of change of velocity, Newton's 1st Law, Law of Inertia, Law of Acceleration, Law of Action-Reaction, Newton's 2nd Law, Law of Inertia, Law of Acceleration, Law of Action-Reaction, Newton's 3rd Law, Law of Inertia, Law of Acceleration, Law of Action-Reaction, An object has a 5N force acting left and a 5N force acting right, what is the NET FORCE?, 10N, 0N, 5N, 25N, An object has two forces opposing each other, one is 200N left and the other is 400N right, what is the NET FORCE?, 200N, Left, 0N, 600N, Right, 200N, Right, When calculating NET FORCE what do you do when two forces are applied in the same direction?, multiply, divide, add, subtract, Force =, mass x acceleration, mass / acceleration, acceleration / mass, speed x time, mass = , Force / acceleration, Force x acceleration, acceleration / Force, What type of force always changes an object's motion?, balanced force, unbalanced force, net force, powerful force, A car turning is an example of, acceleration, balanced forces, constant speed, change in speed, If a boxer with a mass of 50kg punches a bag with a force of 100N how much force does the bag exert on the boxer?, 100N, 5000N, 500N, 2N, What is the mass of a rocket whose engine generates 1000N of force to launch with an acceleration of 20m/s2?, 500kg, 500g, 20000kg, 0.02kg.
