Straight horizontal line 2 of 15 What quantity has the unit m/s squared? Acceleration 3 of 15 What does a negative value for acceleration mean? A deceleration 4 of 15 What happens to the gradient of the line on a distance time graph if the speed increases? The gradient increases 5 of 15 How can an object travelling at a steady speed be accelerating? By changing its direction 6 of 15 A car accelerates from rest to a speed of 40 m/s in 10 s. What is its acceleration? 4 m/s 7 of 15 What part of velocity time graph represents distance travelled? Area between the line and the x axis 8 of 15 What is 10 m/s 9 of 15 A car accelerates from rest to a speed of 40 m/s in 10 s.
