PhysicsForces and MotionGCSEAQA Created by: LSmithCreated on: 25-03-14 20:02 The gradient of a distance-time graph represents... the speed of an object 1 of 18 The velocity of an object is... its speed in a particular direction 2 of 18 The slope on a velocity-time graph represents... the acceleration of an object 3 of 18 The distance travelled is equal to... the area under a velocity-time graph 4 of 18 When an object is moving at a steady speed in a straight line... the line on the graph is straight but sloped 5 of 18 The steeper the line... the greater the speed of the object 6 of 18 Two cars will have different velocities if they are travelling at... the same speed but in different directions 7 of 18 Two cars will have different velocities if they are travelling at... different speeds in the same direction 8 of 18 Two cars will have different velocities if they are travelling at... different speeds in different directions 9 of 18 When an object is moving with a constant velocity the line on the graph is... horizontal 10 of 18 When an object is moving with a constant acceleration, the line on the graph is... straight but sloped 11 of 18 The steeper the line, the _____ the acceleration of the object Greater 12 of 18 A line sloping downwards (a negative gradient) represents... an object with constant deceleration 13 of 18 a = (v – u) ÷ t a=? Acceleration (meters/second squared) 14 of 18 a = (v – u) ÷ t v=? Final velocity (meters/second) 15 of 18 a = (v – u) ÷ t u=? Initial velocity (meters/second) 16 of 18 a = (v – u) ÷ t t=? time (seconds) 17 of 18 The gradient of a line on a distance-time graph represents... the speed of the object 18 of 18
