PPT-Velocity-Time(VT) Graphs

Mr Fedell VT vs PT graphs A positiontime PT graph tells you where an object is A velocitytime graph tells you how fast its moving VT graphs DO NOT give in position info When an object stays still for 10s its velocity is . Equation of Motion for . Average . V. elocity. Position-Time Graphs. P. lot . the time data on a horizontal axis. The . position data on a vertical axis. Position-Time Graphs. Two . different runners. Kinematics Terminology. Scalar vs. Vector. Scalar: . quantities that have only a size, but no direction. i. e. : . distance, speed. Vector: . quantities that have a size and direction. ie. : . displacement, velocity. 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.. Physics. How to interpret a . Position. vs. time Graph. Low on the graph. .. High on the graph. ..

Describing changes in velocity, and how fast they occur, is a part of describing motion.. How are changes in velocity described?. The rate at which velocity changes is called. . acceleration.. Scientists can perform artificial transmutations by bombarding atomic nuclei with high-energy particles such as protons, neutrons, or alpha particles..

Day 1. Warm – Up:. Choose a new seat with . different neighbors.. Get with a partner and discuss: What is motion? How do you know if something is moving?. Write your answers down and be ready for a class discussion.. VS.. SPEED (VELOCITY)/ TIME GRAPHS. DISTANCE-TIME GRAPHS. Plotting distance against time can tell you a lot about motion. Let's look at the axes:. Time is always plotted on the X-axis. (bottom of the graph). . Describing motion is occasionally difficult to do with words. Graphs can help simplify this description greatly. Position = Distance from a starting point. Velocity = rate of change in position. Acceleration = rate of change in velocity. Demonstration.
