P2.1.3 More about velocity-time graphs 0.0 / 5 ? PhysicsMotionGCSEAQA Created by: MaddiCreated on: 04-05-14 14:23 What can we say if a velocity-time graph is a horizontal line? The acceleration is zero. 1 of 5 How can we tell from a velocity-time graph if an object is accelerating or decelerating? The gradient represents acceleration. 2 of 5 What does the area under a velocity-time graph represent? Distance travelled. 3 of 5 If the acceleration is horizontal on a velocity-time graph was does that mean in terms of velocity of the object? The object is travelling at a steady speed. 4 of 5 How does braking affect the velocity of an object? Braking reduces the velocity of the object. 5 of 5
