Q This assignment aligns with the following Unit Objectives: • (U27) Explain and apply Newton's first, second and third laws. (CLO1)(CLO2)(CLO3) • (U33) Discuss the requirements for and consequences of balanced and unbalanced forces (CLO2)(CLO3) • (U35) Identify action-reaction pairs (CLO2)(CLO3) • (UDS) Develop a well thought out and correct response to various discussion questions (CLO2)(CLO3)(CLO5)(Goal 4) Do not start a new thread. Simply reply to my posting. Be sure to comment on at least two of your classmates' postings. Your replies must be more than a simple phrase like "I agree" or "I like your answers". Replies should reflect why you agree or like what has been posted. Your replies must reflect a genuine effort to engage your fellow classmates regarding the comments provided or the problem that has been solved. Please post your answers and replies to the discussion questions below 1. Explain Newton's second and third laws in your own words. You cannot use the word acceleration, give formulas, or use any part of the definitions listed below. 2. Newton's first law states that an object will move with a constant velocity if nothing acts on it. This seems to contradict our everyday experience that all moving objects come to rest unless something acts on it to keep it going. Does our everyday experience contradict one of Newton's Laws? If it does not, explain the apparent contradiction. If it does, explain why we bother to teach Newton's first law anyway. 3. Newton's third law says that objects that touch each other exert forces on each other that satisfy: If object A exerts a force on object B, then object B exerts a force back on object A and the two forces are equal and opposite Consider the following three situations concerning two identical cars and a much heavier truck. • o One car is parked and the other car crashes into it. o One car is parked and the truck crashes into it. o The truck is pushing the car because the car's engine cannot start. The two are touching and the truck is speeding up. Explain how Newton's third law of motion applies to these scenarios. 4. Use Newton's Third Law to explain how goldfish swim. ________________________________________ Need help in using Discussions?
