  2. Forces for 100 A speedboat that pulls a 70kg water skier with a force of 140 Newtons. What is the acceleration of the skier? 2m/s/s BACK

  3. Forces for 200 A force of 5 N is required to increase the speed of a box from 1.0 m/s to 3.0 m/s in 5 seconds along a level surface. If you increased the mass of the box, would it require more or less force? More Force BACK

  4. Forces for 300 A force of 27N causes a satellite to accelerate 3 m/s/s. What is the satellite’s mass? 9kg BACK

  5. Forces for 400 You and your friends need to push a smart car that is 7154N and a truck that is 23000N at the same speed, which vehicle would you have to push with more force? truck. BACK

  6. Forces for 500 A force of 500N acts on three different size objects. One has a weight of 50N, the second object is 100N and the third is 150N. Which will have the greatest acceleration? The 50N object BACK

  7. Graphs for 100 What is the equation to caclulate for slope? Rise / run BACK

  8. Graphs for 200 What is the speed of the object during the first 5 seconds, based on the graph below? 10 m/5 s = 2 m/s BACK BACK

  9. Graphs for 300 Explain what is happening in this graph? Speed is accelerating from 0-10 in 5 seconds. The speed remains at 10m/s for 10 seconds (no acceleration) and then slows down and stops in 5 seconds. BACK BACK

  10. Graphs for 400 Explain the graph below. Travels 10 meters in 5 seconds. Stops for 5 seconds. Travels 5 meters in 5 seconds. Stops for 5 seconds. Travels 10 meters in 5 seconds. BACK BACK

  11. Graphs for 500 Explain the acceleration for each segment of the graph below. Speed (m/s) Accelerates from 0 to 10 in 2 seconds, or 6m/s/s. Goes a constant speed (10 m/s) for 4 seconds. Then decelerates from 10 m/s to 0 m/s. Then stops completely for 2 seconds. BACK

  12. Motion for 100 How can you tell if an object is in motion? If the distance between an object and its reference point changes. BACK

  13. Motion for 200 If a car drives 80 meters in 10 seconds, what is it’s speed? Don’t forget units. Speed = 80m/10s = 8 m/s BACK

  14. Motion 300 A passenger walks towards the rear of a moving train. What is her motion in relation to a reference point on the train? Backwards in relation to a reference point on the train. BACK

  15. Motion 400 If you say the beach is 5Km north and 2 km west, what do you need to know to determine where the beach is? Reference point BACK

  16. Motion 500 Which of the following represents the velocity of an object? a-52 km/hr west b-52km/hr b-52 km c-52 km west a-52 km/hr west BACK

  17. Pressure for 100 How do snowshoes make it easier to walk on snow? Snow shoes increase surface area which spreads out the amount of force you put on the snow BACK

  18. Pressure for 200 The density of a sample of a substance is 30g/cm³, and its mass is 1200 grams. What is the volume of this sample? 40cm³ BACK

  19. Pressure for 300 A student has two containers. Container A holds 1 liter of liquid. Container Bholds two liters of liquid. Both containers are filled with same liquid. Are the densities of the two liquids equal or unequal? The density of the liquid in a container A is equal to the density of container B. BACK

  20. Pressure for 400 What is the density of a solid 1cm long, 0.5cm wide, and 2cm high, if the mass is 6 grams?( remember volume is length x width x height) 6 g/cm³ BACK

  21. Pressure for 500 A rock has a density of 45g/ml and a mass of 90g. What is it’s volume? Density = mass ÷ volume Volume = Mass ÷ density Volume = 90g ÷ 45g/mL Volume = 2 mL BACK

  22. Miscellaneous for 100 What types of things do you find in the results section of a scientific report? Graphs and data tables BACK

  23. Miscellaneous for 200 The force of gravity on a person or an object at the surface of a planet is known as? Weight BACK

  24. Miscellaneous for 300 What causes your weight to b e different on every planet? gravity BACK

  25. Miscellaneous 400 The force of gravity depends on... Mass and Distance BACK

  26. Miscellaneous for 500 What law explains why the planets and Sun are held together as a solar system within the Milky Way galaxy? Law of Universal Gravitation BACK

  27. Final Jeopardy • A ladybug is creeping down a sidewalk at 1 m/s. Sometime later, it’s speeding at 5 m/s. This could have happened if the lady bug accelerated at 1 m/s/s for 4 seconds. Is this the only way that the increase in speed could have happened? Explain. possibilities: 1 m/s/s for 4 s, 2 m/s/s for 2 s, 4 m/s/s for 1 s BACK

  28. Congratulations! Thank you for playing Jeopardy
