PPT-Unit 2 Project: Distance, Displacement, Speed, Velocity, and Acceleration

Name Hour Determine displacement based on distance measurements Calculate speed and velocity based on position and elapsed time Create and interpret distancetime graphs Calculate acceleration based on speed and elapsed time. What Is Motion?. Motion. is when an object changes place or position. To properly describe motion, you need to use the following:. Start and end position?. Movement relative to what?. How far did it go?. “Jeff”, “Mr Jeff”, “Mr C”, “Ciaccio” (See-ah-co) are all fine. Summer Physics Bootcamp. Contact Information. www.MSEAcademics.com. . Cell:770-401-6731. Jeffcia@MSEAcademics.com. . Warm up. 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. . What Is Motion?. Motion. is when an object changes place or position. To properly describe motion, you need to use the following:. Start and end position?. Movement relative to what?. How far did it go?. Use the units of mass, length, and time.. Define displacement, velocity, and acceleration.. Use the units of displacement, velocity, and acceleration.. Measure velocity and acceleration.. Use distance-time and velocity-time graphs.. Chapter 2. Kinematics. deals with the concepts that . are needed to describe motion.. Dynamics . deals with the effect that forces. have on motion.. Together, kinematics and dynamics form. the branch of physics known as . Today’s Learning Objectives. Know the terms in this chapter.. Why is a reference point needed to describe motion?. What is the difference between distance and displacement?. How do you add vectors?. June 2013. June 2013. June 2013. Pure linear motion. Linear motion movement of a body in a . straight. line or . curved line. , where . all parts . move the same distance, in the same direction over the same time.. behaviour. of the universe, from the very smallest scales of sub-atomic particles to the very largest in cosmology. It applies these laws to the solution of practical problems and to the development of new technologies. . 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. Acceleration is a measure of . the change in velocity per unit of time. When the velocity of an object is changing, it is . accelerating. Negative acceleration: . slowing down. Positive acceleration: . V. ector quantity: . magnitude (value) & direction. R. ate . at which an object changes its velocity. . “. How fast an object is getting faster”. If the velocity of an object is changing, it is accelerating!. 2016. Measuring Distance. Meter . – . international unit for measuring distance.. = 50 m. 1 mm. Calculating Speed. Speed. (S) . = distance traveled (d) / the amount of time it took (t). . S = d/t. Displacement: . Is the distance from where you start to where you finish. . Δ. d=. d. f. -d. i. Velocity:. How fast and in what direction (vector quantity). V = ∆d/t. Speed: . How fast (scalar quantity).
