It appears to whip back, but in fact it is remaining still(Newton's 1st Law - Law of Inertia).ġ2) Stopping and starting (acceleration) take more force (energy) than just maintaining a constant speed(Newton's 2nd Law - F = ma). Your body will move forward, while your head remains (momentarily) in place. If you are hit from behind, the seat pushes on your back, but if you do not have a headrest, there is nothing pushing on your head. In order to accelerate around the curve, the door of the car (or seatbelt) pushes on you and causes you to accelerate.ĩ) The head wants to remain at rest. In order to move around a curve, you must change your direction of motion (i.e. The china and glassware want to remain at rest and by pulling quickly, the tablecloth can exert its friction on them for a very short time not enough for them to move.Ĩ) Your natural state of motion is a straight line(Newton's 1st Law - Law of Inertia). When the wagon is pulled, the part of the body that is not touching the wagon will "fall back", really just try and remain in place.ħ) Newton's 1st Law - Law of Inertia.
The voyager space probe has left our solar system on its trip through deep space.Ĥ) The child is at rest and wants to remain at rest (Newton's 1st Law - Law of Inertia). In space this can be directly tested and has been tested many times. Unfortunately we are limited in how long the tube can be. This is Newton's 1 st Law.Ģ) On Earth, we can do very well and reduce friction (including air resistance) in a tube and see an object travel with constant velocity. An object will keep moving in straight-line motion unless acted upon by an external force. Which means that your part, however small, still matters.Homework Solutions Ch 4-8 Chapter4, Chapter5, Chapter6, Chapter7, Chapter8ġ) Yes. The Nepalese are predominately Hindu, a religion that reminds us that we are all one and that life is about harmony and freedom. If you have seen ants build a hill then you know that if we work together there is nothing that can’t be done. Do not hide from this because it seems too big. Finally, but perhaps most importantly, don’t be discouraged by how insurmountable this feels. Amazing organizations like Protect Our Winters, Surfrider Foundation, and 1% For The Planet are keen to utilize all of your extra energy.ĥ.
There is always something that can be done on the home front to staunch some of the bleeding. The people of Nepal will be dealing with this for the rest of their lives let’s keep it in our hearts as well - there is a lot of power in intention.Ĥ. Sardonic stabs at politicians and celebrities should take to the back burner (or, better yet, the trash). Keep this crisis on the forefront of the daily discussion. Participate in the educated spreading of information.
