https://padlet.com/eric_sukiennik/btzeehlzi8qc Group 1,3 answer the following A student writes, “A bird that is diving for prey has a speed of −10m/s.” What is wrong with the student's statement? What has the student actually described? Explain. What is the speed of the bird Group 2 and 4 answer the following:Acceleration is the change in velocity over time. Given this information, is acceleration a vector or a scalar quantity? Explain Group 5,6 and 7 answer: A weather forecast states that the temperature is predicted to be −5ºC the following day. Is this temperature a vector or a scalar quantity? Explain. en-us 2018-10-22 16:25:42 UTC 2026-01-20 12:00:15 UTC hello@padlet.com https://padlet.com/eric_sukiennik/btzeehlzi8qc/wish/295557326 Question 1
the Students statement is wrong because he is not making any statement about in which direction the bird is flying so you do not know about what speed it it speaking. Also speed can never be negative without an direction. He described the vector of the bird.

I think that the student means to describe acceleration. You cannot find speed without knowing the the distance of how far the bird is diving, nor do we have time to calculate.

Acceleration can exist as both a negative and positive quantity and corresponds with velocity which is also a vector. As the velocity of an object increases, the acceleration increases as well, represented by a positive value. When the velocity decreases, the acceleration diminishes, being viewed as a negative amount. The signs of acceleration (positive and negative) indicate an increased or decreased quantity of velocity over time, making acceleration a vector instead of a scalar.]]> 2018-10-22 16:45:03 UTC https://padlet.com/eric_sukiennik/btzeehlzi8qc/wish/295563933 https://padlet.com/eric_sukiennik/btzeehlzi8qc/wish/295563942 1.The student is wrong because the speed is negative and the student described acceleration ]]> 2018-10-22 16:45:04 UTC https://padlet.com/eric_sukiennik/btzeehlzi8qc/wish/295563942 sean_oneal https://padlet.com/eric_sukiennik/btzeehlzi8qc/wish/295564546 the students statement is traveling at a negative speed and that is not possible so it is incorrect.
