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
Forces for 200 More Force BACK 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?
Forces for 300 A force of 27N causes a satellite to accelerate 3 m/s/s. What is the satellites mass? 9kg BACK
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. Forces for 400 BACK
The 50N object Forces for 500 BACK 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?
What is the equation to caclulate for slope? Rise / run Graphs for 100 BACK
What is the speed of the object during the first 5 seconds, based on the graph below? 10 m/5 s = 2 m/s Graphs for 200 BACK
Graphs for 300 BACK 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
Graphs for 400 BACK 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
Explain the acceleration for each segment of the graph below. 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. Graphs for 500 BACK Speed (m/s)
Motion for 100 How can you tell if an object is in motion? BACK If the distance between an object and its reference point changes.
Motion for 200 If a car drives 80 meters in 10 seconds, what is its speed? Dont forget units. Speed = 80m/10s = 8 m/s BACK
Backwards in relation to a reference point on the train. Motion 300 BACK A passenger walks towards the rear of a moving train. What is her motion in relation to a reference point on the train?
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
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 Motion 500 BACK
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
Pressure for 200 The density of a sample of a substance is 30g/cm, and its mass is 1200 grams. What is the volume of this sample? 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
A student has two containers. Container A holds 1 liter of liquid. Container B holds 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. Pressure for 300 BACK
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
Pressure for 500 BACK A rock has a density of 45g/ml and a mass of 90g. What is its volume? Density = mass ÷ volume Volume = Mass ÷ density Volume = 90g ÷ 45g/mL Volume = 2 mL
Miscellaneous for 100 What types of things do you find in the results section of a scientific report? Graphs and data tables BACK
Miscellaneous for 200 The force of gravity on a person or an object at the surface of a planet is known as? Weight BACK
What causes your weight to b e different on every planet? gravity Miscellaneous for 300 BACK
Miscellaneous 400 The force of gravity depends on... Mass and Distance BACK
What law explains why the planets and Sun are held together as a solar system within the Milky Way galaxy? Law of Universal Gravitation Miscellaneous for 500 BACK
Final Jeopardy A ladybug is creeping down a sidewalk at 1 m/s. Sometime later, its 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. A ladybug is creeping down a sidewalk at 1 m/s. Sometime later, its 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
