A ball falling from rest is located 45 m below its starting point 3. Cpo physics textbook and laboratory book types of materials. We either know the velocity or acceleration, or the dependence of velocity on time or acceleration on time, but we need to find something else about this motion. In general, you will always choose the equation which contains the three known and the one unknown variable. When a particle moves at a constant speed, its rate of change of distance remains. In the diagrams below, a ball is on a flat horizontal surface. Ieee transactions on robotics 1 path planning under. Differentiate between, and give examples of, scalar and vector quantities.
Projectile motion problems are the same as problems from the last chapter except that you have two sets of equations, one for the horizontal motion and one for the vertical motion. Kinematic curve analysis consider the following velocity vs. Also why this class is called kinematics and dynamics. It is advised that students attempt to solve each problem before viewing the answer, then use the solution to determine. When its rockets are fired it experiences an acceleration. Relativity kinematics two topics, kinematics and dynamics. The next step of the strategy involves identifying a kinematic equation which would allow you to determine the unknown quantity.
