acceleration in day to day life essay
Answers
Answer:
Noone teaching mechanics in school or in undergraduate physics can fail to notice how the concepts of force and acceleration cause problems for students. Physicists, who are used to studying the fundamental interactions in Nature, may be fascinated by students' common ways of discussing friction, normal force and centripetal force as fundamental forces in their own right.
Newton's discovery of the laws of motion changed the way we view our universe. The laws are a standard part of any physicist's toolbox. They are also among the most studied part of physics education and there is an overwhelming body of evidence that students often fail to master even the most basic aspects (see e.g. McDermott, 1998, McDermott and Redish, 1999, Redish, 2003). Can anything new be added to the research on learning and teaching mechanics? What if there is something fundamentally wrong in the approach to force and acceleration in school physics?
The laws of motion are traditionally introduced through non-motion, discussing forces on a system at rest. The study of forces then moves on to situations where all forces cancel. If the body is not at rest, it thus remains in uniform rectilinear motion and Newton's first law seems to contradict everyday experience, where a cyclist needs to pedal to keep going, and a car comes to rest unless the engine continues to provide energy.
Answer:
Some good examples of acceleration related to daily life are: When the car is speeding up. When the car slows down. ... The car turning at the corner is an example of acceleration because the direction is changing
