Physical Science Week 15 Force & Motion Monday Warm Up (127) • Kira jogs 72 m away in a time of 36 s. What is Kira’s average speed? • If you walk 7.5 km in 1.5 h, what is your average speed? Assignment • Newton’s law power point – completion • Newton’s law – choice board activity. Type in MS Word or put at end of ppt. Newton’s Laws • Make a power point with the 4 laws (1, 2, 3, and universal gravitation) • Include pictures with explanations of how it shows each law. • Include how the laws apply in each of the lab stations we completed Monday and Tuesday. Tuesday Warm Up (127) • A plane passes over point A at a velocity of 240 m/s north. 40 seconds later the plane passes over point B at 260 m/s north. What is the plane’s average acceleration? • Hint: look up formula for average acceleration in IAN. Force & Motion Lab Stations Wednesday Warm Ups (127) • If your weight is 12 N on earth and your mass is 150 kg, what is your mass and weight on the moon if the gravity there is 1/6 the gravity found on earth? Force & Motion Cafe • Choose one appetizer, one entrée, and one dessert. Thursday Warm Up (127) • A marble rests on top of a tall building. The marble falls and hits the ground in 4.5 seconds. What is the marble’s velocity at the time it hits the ground? • Hint: What is acceleration due to gravity? Study Guide • • • • • • Speed Velocity Acceleration Force, balanced, unbalanced, net force Inertia, gravity, momentum Newton’s laws Friday Warm Up • Study silently five minutes before test.
