Assertion: A body has a non-uniform motion, if it travels unequal distances in equal intervals of time. Reason : In non-uniform motion, the body covers equal distance in unequal intervals of time. AIf both assertion and reason are true and reason is the correct explanation of assertion. BIf...
The motion of an object is defined by some parameters as its velocity or by its acceleration. Motion may be uniform or non- uniform depending on certain characteristics.Answer and Explanation: Motion is the act or the process of an object of changing its position. The motion may be unifor...
How is non-uniform motion different from uniform motion? View Solution What will be bature of velocity-timegraph for a uniform motion? View Solution What parameter can be determined from velocity-time graph of uniform motion? View Solution What can be deduced from the slope of a position-tim...
Rotational motion refers to anything spinning or moving in a circular path. It is also called angular motion or circular motion. The motion may be uniform (i.e., the velocity v doesn't change) or non-uniform, but it has to be circular. The revolution of the Earth and other pla...
What is the equation for Newton's second law of motion? What direction does the acceleration vector point in uniform circular motion? Define centripetal force Is there centripetal force in uniform circular motion? An object's moment of inertia is 1.50 kg.m^2. Its angular velocity is increasing...
fill the gaps in our understanding of the universe. The European Organization for Nuclear Research(CERN), the largest particle physics laboratory in the world, is also on a quest to find missing dark matter particles. NASA discusses the difference between dark matter and dark energy inthis ...
The first one is obvious –training and experience. You don't expect a lawyer, however bright he may be, to give you a new theory of physics these days or mathematics or engineering. 第一个要素,很明显——是培养及经验。 你不会指望一位律师——无论他有多么聪明——都能分分钟给出一个现在...
This allows SR to view all motion to be uniform, meaning constant velocity (non-accelerating). The second point is that SR is a "special" theory. By this, I mean that it is applicable in situations where there is no gravity, hence where space-time is flat. In GR, Einstein unifies ...
In solid materials, particles are tightly packed, which means they have a high density. This curtails their movement. Moreover, the electrons in each atom are in constant motion, so the atom has a small vibration. Nonetheless, its position remains fixed, which is why solid particles have low...
A physics major is a science degree path that helps explain how the world works and how the universe is structured. Majors study matter and energy and gain exposure to both classical and modern theories in the field. Students also spend time completing experiments in a lab setting. With the ...
