Unit 7 Activity 1: Two-dimensional Motion and Forces To show and then play a movie, click on the arrow or the movie title/description. Repeat to hide it. Exploration #1, STEP 2: Simulation of race between two balls in +y-direction. Force is applied to one in the +x-direction. Exploration #1, STEP 2: Simulation of race between two balls in +y-direction. Force is applied to one in the +x-direction. Vectors in two dimensions: Vectors simulator. Vectors in two dimensions: Vectors simulator. You should be able to run this yourself! Click on the image below and follow the instructions in the activity. This simulator is one of many developed by the Physics Education Technology (PhET) group at the University of Colorado at Boulder. Exploration #2, STEP 2a: Simulation of ball moving in +y-direction, with a force applied in +x-direction. Exploration #2, STEP 2a: Simulation of ball moving in +y-direction, with a force applied in +x-direction. Exploration #2, STEP 2b: Simulation of ball moving in +y-direction, with more forces applied in +x-direction. Exploration #2, STEP 2b: Simulation of ball moving in +y-direction, with more forces applied in +x-direction. Exploration #2, STEP 3: Simulation of ball moving in +y-direction, with more forces applied in -y-direction.
