How to Know Which Kinematic Equation to Use
There are 5 kinematic equations and 5 variables. This is certainly equation 1. Kinematics Equation Physics Classroom Equations Physics 1why is it better to use the equation they did. . Identify the starting and final velocities of the object. The slope of the line can be computed using the rise over run ratio. There are four kinematic equations when the initial starting position is the origin and the acceleration is constant. Identify the objects final velocity and position. The answer book used xxovot12at2 and got 408 s. This problem has been solved. Δd Vot 12 at 2. For example if the question does not include time then you need to use a kinematic equation that does not have t in it. V 2 v 1 aDelta t To get the next formula one must first derive an expression for the displacement of the object. V v 0 at. D12 v0vt d 1 2 v 0 v t or alternatively vaveragedt. Δd 12 Vo Vft. St...
