Common Mistakes in Kinematics - What To Do and Not to Do

In this video we review kinematics and common mistakes that students make when solving kinematics problems in physics. 0:00 - Definitions Describing Motion 2:11 - Does Same Position = Same Velocity? 3:16 - Direction of Acceleration when Velocity = 0 7:50 - Possible Values of Position, Velocity, and Acceleration 10:50 - Acceleration Possible if Not Speeding Up of Slowing Down? 15:17 - Does Positive Acceleration = Speeding Up? 17:50 - Relative Directions of Velocity and Acceleration 19:45 - Graphing Functions 21:36 - Relationships of Position, Velocity, & Acceleration Graphs 24:25 - Slope at a Single Point 27:40 - Constant Value vs. Constant Slope 29:57 - More Relationships and Units of Graphs 32:26 - Area Under a Curve 35:31 - Relative Motion from Same Graph 37:10 - Fastest Speed, At Rest, Slowing Down & Changing Direction From Graphs 40:26 - Velocity from Position Graph Example 43:10 - When Do Problems Start and End? 46:37 - Projectile Motion Problem Solving
