Resultant Forces 0.0 / 5 ? PhysicsForces and MotionGCSEAQA Created by: LSmithCreated on: 25-03-14 19:49 If an object remains stationary if the resultant force acting on it is... zero 1 of 15 If an object is moving and has a resultant force of zero, it keeps moving at... the same speed in the same direction 2 of 15 If the resultant force acting on an object is not zero, a stationary object... begins to accelerate in the same direction as the force 3 of 15 A moving object speeds up, slows down... or changes direction 4 of 15 Acceleration depends on... the force applied to an object and the object’s mass 5 of 15 What is a resultant force? A single force that has the same effect on the object as all the individual forces acting together 6 of 15 In a force diagram, the longer the arrow... the bigger the force 7 of 15 When there is a non-zero resultant force... the object accelerates in the direction of the resultant force 8 of 15 When there is a non-zero resultant force, a stationary object begins to move... in the direction of the resultant force 9 of 15 When there is a non-zero resultant force, a moving object... speeds up, slows down or changes direction depending on the direction of the resultant force 10 of 15 An object will accelerate in... the direction of the resultant force 11 of 15 The bigger the force... the greater the acceleration 12 of 15 A force on a large mass will accelerate it ____ than the same force on a smaller mass Less 13 of 15 Doubling the mass _____ the acceleration Halves 14 of 15 F = m × a What is the acceleration of a 10 kg mass with a 50 N resultant force acting on it? 50 ÷ 10 = 5 m/s2 15 of 15
