hsphetcolorado.edufenfsimulationj'forces-and-motion-basics Select Acceleration. Set the Friction to None (and make sure re-set it to zero for each run). Click and drag the person toward the wooden box to apply a force on it. You can select to display a physical quantity using the table on the top right corner. Answer the following questions: 4. As you apply a constant force, what happens to the speed? a) Sometimes Increase b) Remains same c) Can't be answered without knowing the mass d) Decreases e) Increases 5. Now to maintain a constant speed what should you do? a) None of the above b) First increases then decreases the applied force and continue to apply a smaller force then you started with c) Increase the applied force (1) Stop applying force e) Decrease the applied force 6. When you decrease the applied force what happens to acceleration? Set the applied force to a x value. a) First decreases and then increases b) Increases c) Decreases d) Remains same e) First increases and then decreases 7. Take 50 kg mass and note the value of acceleration. Now, double the mass by adding a second wooden box on top, what happens to acceleration? a) Depends on shape of the object b) Acceleration remains the same c) Acceleration gets doubled d) More information is required e) Acceleration is reduced to half 8. Take 200 kg mass and note the acceleration. Now decrease the mass by factor of two, what happens to acceleration. a) Acceleration remains the same b) Acceleration gets doubled c) More information is required d) Acceleration reduced to half e) Depends on shape of the object 9. From the above-mentioned simulation state the relationship between mass and acceleration for constant applied force. a) Acceleration is directly proportional to mass of the object b) Acceleration is independent to mass of the object o) All of the above (1) Acceleration is inversely proportional to mass of the object e) None of the above 10. With the friction set to zero, does the object need a force for it to move at constant speed? a) Yes b) No
