PPT-Average Velocity PowerPoint 8.2

Speed versus Velocity scalar quantity Magnitude and direction Magnitude but no direction The SI units for both and is ms but kmh is also utilized   Speed is the . Kinematics. is the branch of physics that describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion.. Kinematics. One-dimensional kinematics involves movement along one axis.. Motion. Motion is the change in an object’s position (or location) relative to a . reference point. .. A . reference point . is an object that appears to stay in place.. Sometimes the change in distance from a reference point to an object can be measured. . Physics 4A . Spring 2015. Chapter 2. Motion Along a Straight Line!. Goals for Chapter 2. Describe . straight-line motion. in terms of . velocity. . and . acceleration. Distinguish between . average. We’ve talked about how a derivative can be used to find the slope of a tangent line.. The derivative can also be used to determine the rate of change of one variable with respect to another. Or the . of the Madeira River in Brazil. Christine . Bonthius. The University of Texas at Austin. Department of Geography and the Environment . cmbonthius@gmail.com. Goals of Term Project . Inventory . hydraulic variables from ADCP data. Essential Question: How do you calculate the displacement and velocity of an object?. What is mechanics?. The branch of physics concerned with motion and forces.. The subset of mechanics that describes motion without regard to its causes is called kinematics.. distance. traveled in a given time. Speed is a . scalar. Velocity (v): change of . position. over time. Velocity is a . vector. Where . Δ. means “change in” or final – initial. Average speed. Velocity and acceleration Measuring an objects motion speed Speed is calculated by dividing distance by time S = d/t 5.0 km/h 2.5 m/s 45 mph velocity Velocity is the same as speed, but you tell the direction of motion in the answer. .

The FOREWORD This report is one of several to be published from research conducted under NASA Contract NAS8-26751 entitled Cloud Motion in Relation to the Ambient Wind Field This effort is sp Velocity is a vector, speed a scalar. Average speed – total distance divided by time. Average velocity – total displacement divided by time. Speed and velocity may or may not have the same magnitude. Lesson . 2. Position with Constant Acceleration. The graph shows that the car’s motion is not uniform: The displacements for equal time intervals on the graph get larger and larger.. The slope of a position-time graph of a car moving with a constant acceleration gets steeper as time goes on..
