Document Summary

Kinematic problems requiring you do nd an object"s velocity after acceleration, it"s displacement during acceleration, the time it took for the acceleration to go from v1 to v2, are solvable. They"re all correlated through these 5 equations, allowing you to solve for your unknown variable. These equations are the only 5 needed for kinematic problems involving acceleration. If there is no acceleration involved (no in velocity"s magnitude or direction), then use v=d t. Interpreting graphs: a graph plotting velocity against time will give total displacement of an object, the area under the graph, calculated through t v(t, example, let north be positive and south be negative. The velocity from t=0 to t=30 is positive, and can be calculated by fragmenting the graph and adding the sum. The acceleration a = f/m is in the direction of the force and proportional to the magnitude of the force.
