- To find the simulation, either Google “Phet simulation vector addition” or go directly to this link: https://phet.colorado.edu/en/simulation/vector-addition
- Click “Explore 2D”, “Lab”, and “Equations”.
- Spend 10 minutes just playing with the simulation to see what it can do.
- When you are done answering this activity, kindly save your file in pdf format and name it Activity 1_LastName. For example, A1_Singson.
ACTIVITY 1: VECTOR ADDITION
Cities of Mandaluyong and Pasig PHYSICS FOR ENGINEERS - LABORATORY Exedy C. Lampara Part A Double click Lab tab. Drag the center of the coordinate at the center. Hit the Component Displays , Values , and Angle. These buttons will show the components of the vector Situation 1: [5pts] Suppose you are driving 19.2kph with a compass reading 51.3˚ north of east. Represent the vector using simulation. a. Screenshot/Print-screen the simulation and paste it here. b. How fast is your car traveling in the north direction? How fast in the east direction? The car travels about 15.0 kph North and 12.0 kph East.

Cities of Mandaluyong and Pasig PHYSICS FOR ENGINEERS - LABORATORY Exedy C. Lampara Part B (^) At this point, choose the “Equation” tab to do the simulation. Click Base Vectors to change the values of the components. Situation 3: [5pts] The vector A has 6.0m x-component and 10.0m y-component. a. What is the magnitude and direction of vector A? Given the two components of Vector A (6.0m x-component and 10.0m y-component). The Vector A has a magnitude of 11.7m and the direction of Northeast. b. Screenshot/Print-screen the simulation and paste it here.
Cities of Mandaluyong and Pasig PHYSICS FOR ENGINEERS - LABORATORY Exedy C. Lampara Situation 4: [5pts] Vector B has 8.0m x-component and -4.0m y-component. a. Adding the vectors A in Situation 3 and B , what is the magnitude and direction of resultant vector? After adding Vector A (6.0m x-component and 10.0m y-component) with Vector B (8.0m x- component and -4.0m y-component). The resultant Vector C has a magnitude of 15.2m and the direction of Northeast. b. Screenshot/Print-screen the simulation and paste it here. Generalization: What is a vector? How will you add vectors? Vector is a quantity that depicts two independent properties: magnitude and direction. On the other note, the opposite of vector is called scalar, which only describes magnitude but with no specific direction. An example of vector are acceleration and force since when a force is applied to an object, there is always a direction the force will go through. Adding or subtracting magnitudes together will result to the addition or sum of vectors with the same direction.
