Kinematics Equations Chapter for constant velocity 2 or constant acceleration , to o V at t St = Vo + = Kinematics in one Dimension X = Xo + Vt + Eat v vo= + 2a(X - Xo) =No mechanics -> study of motion of objects + related concepts of force + energy 2 X = vt + x0 + X = mx + b 1 kinematics > - how objects move 2 Dynamics -> why objects move translational motion - objects that move without rotating reference frame - any measurement of position , distance or speed must be made with respect to this position is given by its X coordinate Distance > - total path of object Average Speed -> total distance traveled along its path divided by the time it takes to travel this distance distance traveled = time elapsed Displacement- how far the object is from its starting Point · has magnitude + direction - I DX = Xf - Xi & Vector velocity => Slope instantaneous Velocity -> signify both magnitude + direction velocity > tangent average velocity = displacementa b v - are velocity v - instant velocity Instantaneous Velocity - average Velocity over an infinitesimally short time Interval v = sim · Instaneous speed always equals the magnitude of the Instanteous velocity Acceleration - how rapidly the velocity of an object is changing - magnitude + direction acceleration = units dimensions average = instantaneous acceleration - a = sim free V at falling : = Vo + acceleration due to gravity -> at a given location on Earth+ in absence of air resistance all objects fall with same constant acceleration ,
