PART A: 1. Using your mobile learning device, open this link: https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and-motion- basics en.html 1. You will see four icons on the screen. Click the second one which says "Motion". You will see the simulation on "Motion" as shown below: 200 kg Speed [0.0 m/s 50 kg -500 50 kg Applied Force 0 Newtons 7 500 40 kg sko ✔Force ✔Values ✔Masses Speed II 100 kg ? 3. Keep all the items inside the yellow box (upper right-hand corner) ticked. 4. Choose a particular item from bottom left/right boxes and position it on top of the skate board. 5. Set the "Applied Force" as 50 N ("N" stands for "Newton", a unit of force) by clicking/tapping on the right arrow opce. Observe the motion of the box within 10-15 seconds. You may look at how fast the value of speed changes, as shown in the circle on the upper left corner. 6. Without changing the chosen item on the skateboard, set the applied force into higher values (from 50 N, to 100 N, 150 N, 200 N...) by clicking/tapping on the right arrow. Observe the motion of the object for at least 10 seconds for each value of applied force. Carefully notice how fast the value of the speed changes for each value of force applied. PART A GUIDE QUESTIONS: a. What happens to the change in the value of the speed as you increased the amount of force applied on your chosen item? b. What does this observation tell you about the relationship between the external force applied and the object's acceleration (the rate of change in velocity)?
