It also depends on what kind of acceleration is taking place ... continuous change of speed or continuous change of direction.
-- If the graph shows speed vs time, and the acceleration is a change in speed, then the graph is a connected series of straight-line pieces. Each straight piece slopes up if speed is increasing, or down if speed is decreasing.
-- If the graph shows speed vs time, and the acceleration is a change in direction only, then the graph is a straight horizontal line, since speed is constant.
-- If the graph shows direction vs time, and the acceleration is a change in speed only, then the graph is a straight horizontal line, since direction is constant.
-- If the graph shows direction vs time, and the acceleration is a change in direction, then the graph is a connected series of pieces of line. Each piece may be straight if the direction is changing at a constant rate, or curved if the direction is changing at a rate which grows or shrinks. Each piece may slope up if the angle that defines the direction is growing, or may slope down if the angle that defines the direction is decreasing.
-- If the graph shows distance vs time, and the acceleration is a change in speed, then the graph is a connected series of pieces of curves. Each piece curves up if speed is increasing, or down if speed is decreasing.
-- If the graph shows distance vs time, and the acceleration is a change in direction only, then the graph is a straight line sloping up, since speed is constant.
Answer: Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light. In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants.
If you decrease the height of the diving board, you will create less energy because you will build up less acceleration jumping from a lower height. Hope this helps ya!
