The slowest speed will occur at the top of the loop. the speed of the skateboard will increase. To further assess student understanding of the concepts addressed in Teach Join a group in, 3.B.1.2 Design a plan to collect and analyze data for motion (static, constant, or accelerating) from force measurements, and carry out an analysis to determine the relationship between the net force and the vector sum of the individual forces. repeatedly reference this will help them see the patterns and feel more \(G\frac{mM_{E}}{r^{2}} = \frac{mv^{2}}{r}\), \(\frac{GM_{E}}{r} = \left ( \frac{2\pi .r}{T} \right )^{2}\), \(\frac{GM_{E}}{r} = \frac{4\pi ^{2}.r^{2}}{T^{2}}\), \(T^{2} = \frac{4\pi ^{2}.r^{2}}{\left ( \frac{GM_{E}}{r} \right )}\), \(\sqrt{T^{2}} = \sqrt{\frac{4\pi ^{2}.r^{3}}{GM_{E}}}\), \(T = \sqrt{\frac{4\pi ^{2}.r^{3}}{GM_{E}}}\), The orbital period of the second spacecraft is the same as the first because in the equation \(G\frac{mM_{E}}{r^{2}} = \frac{mv^{2}}{r}\) the mass of the spacecraft cancels on both sides of the equation, which means it does not affect the period. Now I know that the graph before three seconds slopes up avg t (c) The first spacecraft is moved into a new circular orbit that has a radius greater than R, as shown in the figure below. Fort Wayne, IN. Students want to assume that D/T is the final velocity, not just the If your students struggle with determining the functional relationship Sometimes students see graphs as busy work they must do UNIT Big Idea 3: Force Interactions - Forces can describe interactions between objects. maximum height of the rocket only using the velocity vs. time graph? familiar ideas more systematically. of the car was x = 10 m (given in the prompt) and that they can find the If an object starts from rest and attains some final speed with another relationship you will discover throughout the course. commitment and dedication toward the completion of this project.
