Straight horizontal line 2 of 12 What quantity has the unit m/s squared? Acceleration 3 of 12 What does a negative value for acceleration mean? A deceleration 4 of 12 What happens to the gradient of the line on a distance-time graph if the speed increases? The gradient increases 5 of 12 How can an object travelling at a steady speed be accelerating? By changing its direction 6 of 12 A car accelerates from rest to a speed of 40m/s in 10s. What is its acceleration? 4 m/s squared 7 of 12 What part of a velocity-time graph represents distance travelled?
