Straight horizontal line 2 of 14 What quantity has the unit m/s squared? Acceleration 3 of 14 What does a negative value for acceleration mean? A deceleration 4 of 14 What happens to the gradientn of the line on a distance-time graph if the speed increases? The gradient increases 5 of 14 How can an object travelling at a steady speed be accelerating? By changing its direction 6 of 14 A car accelerates from rest to a speed of 40 m/s in 10 s. What is its acceleration? 4 m/s squared 7 of 14 What part of a velocity-time graph represents distance travelled? Area between the line and the x-axis 8 of 14 A car accelerates from rest to a speed of 40 m/s in 10 s.
