PPT-Displacement, Time, and Velocity

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. Using the equations on the board, answer the following questions on a sheet of paper. . 1. What equation would you use to solve for the height of a building that you drop a penny off of?. 2. What equation would you use to solve for final velocity of a moving car?. In maths, words can be very important and sometimes have a more specific meaning than we first think.. For example, if we talk about ‘doing a sum’, many people think this means the same as a ‘doing a calculation’, but ‘sum’ means ‘addition’, so 7-3=4 is not strictly a ‘sum’ at all.. M. echanics. - the study of the motion of objects. we focus on the language, principles, and laws that describe and explain the motion of objects. Kinematics. is the science of describing the motion of objects using words, diagrams, numbers, graphs, and equations. . Kinematics. Terms . Distance – the total measured path that an object travels. (scalar). Displacement – the measured straight line distance from when the object starts to where it ends. (vector, watch for negatives). Chapter 2. Kinematics: Description of Motion. Warmup. : . Movin. ’ On. Acceleration . refers to any change in an object’s velocity. . Velocity . not only refers to an object’s speed but also its direction. The direction of an object’s acceleration is the same as the direction of the force causing it.. Unit 42. Vibrationdata. Accidental Drop Shock. Half-Sine Shock on Drop Tower.

The subset of mechanics that describes motion without regard to its causes is called kinematics.. 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.
