What is the acceleration when using suvat equations? correct answers Constant On a displacement time graph what is the gradient? correct answers Velocity On a displacement time graph where is the starting point? correct answers On the x axis On a displacement time graph when is it below the x axis? correct answers Past the starting point What does a velocity time graph have when it is a straight line? correct answers A constant velocity What is the area under a velocity time graph? correct answers Displacement What is the gradient on a velocity time graph? correct answers Acceleration What does it mean when the graph goes below the x axis on a velocity time graph? correct answers The velocity is in the other direction so the object moves backwards On a displacement time graph, what does it mean when the graph is horizontal? correct answers The object is stationary What does a positive curve mean on a displacement time graph? correct answers Gradient/Velocity increasing so the object is accelerating On a displacement time graph, how do you find the average velocity? correct answers Divide the total displacement s by the time taken t On a displacement time graph, how do you find the instantaneous velocity at a point? correct answers Gradient at a point. You find this by drawing a tangent to the curve and calculating its gradient. How do you find the area under the curve/ total displacement on a velocity time graph? correct answers Count the squares by putting a dot in every square so you get the marks for counting them. The displacement = the area of 1 square x total number of squares. Where should the hunter aim to hit the monkey? correct answers The hunter should aim directly at the monkey as vertical and horizontal motion are independent of each other. What do I need to remember when drawing a vector polygon? correct answers When one vector ends, the next vector starts. What does a closed vector polygon mean? correct answers The quantities are in equilibrium.
