PPT-Lesson 2.1 Displacement and Velocity

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.

Time measured by a stopwatch from sound of gun.. Initial speed will be zero. . Recap - Linear Motion Descriptors. Introducing Angular Motion. Angular motion is . the movement of a body (or a body part) in a circular path about an axis of rotation. .. Angular Motion and Force. Think…. Describe the speedometer on a car that is entering a highway, drives for 25 miles and then exits the highway.. Consider the two situations below. When a shuttle bus approaches a stop, the driver begins to apply the brakes to slow down 5.0 s before actually reaching the stop. The speed changes from 9.0 m/s to 0 m/s over time.. Distance vs Displacement. Distance – the total amount traveled.. Displacement – the total amount displaced from the starting point.. Solving Problems. Organize the Information. Sketch the scene. Verify Units. Know . The definition of scalar and vector quantities. Understand. Concept of distance, displacement, speed and velocity. Be able to . Determine distance and displacement in a given situation with units. Displacement, Velocity, and Acceleration are the three vector quantities that describe the motion of any object during a specified time interval.. Vectors – Quantities that have . magnitude . and direction.. Definitions . Speed. : speed of an object is define as the distance traveled by it per unit time .I.e. speed of an object tells us how fast an object moves. Expression for speed : let distance traveled by an object be S in time t .then. Examples should include: . velocity/speed, mass, force/weight, acceleration, displacement/distance. . Addition of vectors by calculation or scale drawing. . Calculations will be limited to two vectors at right angles. Scale drawings may involve vectors at angles other than .
