**Completion of this assignment is going to require that you describe the following force terms: normal force, friction force, net force, gravitational force. **A force is a push or pull between two or more objects of mass. 1. Normal Force Description:__________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ Phet simulation: Ramp https://phet.colorado.edu/en/simulation/the-ramp How the simulation shows the force: _____________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ 2. Friction Force Description:__________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ Phet simulation: Ramp Forces and Motion https://phet.colorado.edu/en/simulation/ramp-forces-and-motion How the simulation shows the force: _____________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ 3. Net Force Description:__________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ Phet simulation: Balancing Act https://phet.colorado.edu/en/simulation/balancing-act How the simulation shows the force: _____________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ 4. Gravitational Force Description:__________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ Phet simulation: My Solar System https://phet.colorado.edu/en/simulation/my-solar-system How the simulation shows the force: _____________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ____________________________________________________________________________________________________________ ******FURTHER UNDERSTNDING**** THIS WILL BE ON YOUR TEST! The gravitational attraction between two objects is dependent on____________________ and ____________ As an object falls toward Earth, air resistance due to the atmosphere gradually increases until acceleration of the object is equal to 0 m/s. What has the objected reached? As a satellite is launched into orbit, how does Earth’s gravity affect the satellite as it travels away from Earth?

Why was Rosetta in interplanetary space for so long? 3. Look up what a comet is described as. Having read that description how would you describe a comet in your own words? 4. What comet 67p the intended target from the beginning of the mission? 5. Why do scientists believe comets need to be studied? 6. What data was Philae able to send back? 7. Was/Is the mission a total failure? 8. Is Philae going to come back online? nd 9. What role does Newton’s 2 law play?
