Click the Play button: Describe the shape of the orbit. Describe the magnitude of the velocity vector: PAUSE and RESET. Drag the planet closer to the star. Describe the shape of the orbit. Describe the magnitude of the velocity vector: PAUSE and RESET. Drag the planet farther from the star. Describe the Shape of the orbit. Describe the magnitude of the velocity vector: PAUSE and RESET. Increase the velocity of the planet. You can do this by dragging on the planet's velocity vector. Describe how the planet moves. What is different? PAUSE and RASSY. Decrease the velocity of the planet below its original value. Describe how the planet moves. What is different? PAUSE and RESET. Decrease the star mass to 0.5. Describe how the planet moves. What is different? PAUSE and RESET. Decrease both the star and the planet mass to 0.5 Describe how the planet moves. What is different? PAUSE and RESET. Increase both the Star and the planet mass to 1.5 Describe how the planet moves. What is different?ANALYSIS . . - 'P 1. Which ofthe tested parameters had the greatest effect on the speed of the orbiting obJECt. Which had the least effect? 2. Derive the formula for the speed of a circular orbit. 3. Look up the mass of the Sun and the distance from Earth to the Sun (both are in the textbook, or you can search online). Use these values to calculate the orbital speed of the Earth in m/s. Also convert your answer into mph
