How Will it Move?Common AssessmentFor the next two questions, refer to the picture on the right. Amagnet is floating motionless above another magnet in acontainer.1. What are the two forces acting on the upper magnet?Gravitational force and magnetic force.2. What is the relationship between the force the lower magnetapplies to the upper magnet and the force the upper magnet applies tothe lower one?They repel each other because of the magnetic force.For the next question, refer to the picture below:3. Why is the box sitting on the table not moving?The box is not moving because the normal and gravitational force is balanced.4. A skydiver jumps out of an airplane and the parachute opens. Describe the forces that are nowimpacting the skydiver’s descent.There were gravitational and air resistance. The forces were unbalanced because theskydiver was going down which means that the gravitational force was stronger.For the next question, please refer to the following image of a magneticcannon:
5. Steel ball bearing #1 is approaching magnet #1 through magnetic attraction.The rest of theball bearings are not in motion yet. Then, we observed ball five traveling away from themagnets. Why does the magnetic cannon function in this manner?The magnetic cannon functions in this manner because Ball one becomes attracted toMagnet one because of the magnetic force and Ball 5 travels away because of the potentialenergy.6. Maria pushes on a heavy boulder, but the boulder does not move. Why does the boulder notmove?The boulder doesn’t move because of the boulder’s frictional force and Maria’s applied force isbalanced.7. When the ball is on its way down through point A, what force(s) are acting on the ball?Gravitational force, air resistance8. Afterbouncing back up and moving upthroughpoint B, what force(s) are acting on the ball?Gravitational force, air resistance9. While playing air hockey at Bowlero, Madison observes that the air hockey puck is floating in the airjust above the air hockey table. The puck is not moving from side to side. What can she conclude aboutthe force(s) acting on the puck?The forces are balanced. The forces are gravitational force and air force.10. As Amelia hits a puck across the wooden gym floor, she observes the speed of the puck. Which of
the following observations is most likely?Friction will make it slow down and it will move in the direction that Amelia hit it.11. Two magnets in the picture below are attracting each other. The big magnet attracts the smallmagnet with:a greater magnetic force12. After raking a pile of leaves under a tall branch, you decide to climb the treeand jump into the pile. Why do you not get hurt from jumping from such a tallheight into a pile of leaves?I don’t get hurt because the pile of leaves is absorbing most of the force when you land inthe leaves and the elastic force is there because the leaves compress when you land whichslows your acceleration.13. Your friend is walking along the edge of a pool. You think it would be funny if your friendwent for a swim. Based on the laws of motion, how are you going to ensure your friend takes adive into the pool?You have to apply a greater force than their static friction in the direction of the pool.14. An object’s mass is 500 g. What is the weight on Earth?5N15. What is the difference between mass and weight?Weight changes depending on location and mass never changes. Weight is the measurementof the gravitational force pulling down on something, while matter is what makes up theobject.
16. What could have occurred during 0 and 3 seconds?Something is going up the hill in those three seconds.17. What variables are being represented in the graph?Elevation for hill and time in seconds.18. What may have occurred to explain the time from 7 seconds to 16 seconds?Going down the hill.The following model explains the motion of an object. Use the model toanswer questions 19-21.
For the following question, use the image below.22.Draw one free body diagram for each of the scenarios. Label all forces being appliedtotheCART. Label diagrams A., B., C.Scenario A. The man on the right, Luke, is pushing with greater force than the man on the left, Han.Scenario B. The man on the left, Han, is pushing with greater force than the man on the right, Luke.Scenario C. The man on the right, Luke, is pushing with the same force as the man on the left, Han.Scenario AScenario BScenario C
