A) No, the equations presented above are the product of the derivation of position and velocity when the acceleration is constant.
The equations change to polynomial function of the second degree for the description of the acceleration when described as a function of time.
B) Yes, when the acceleration is zero it is concluded that the velocity is constant, therefore they could be used to describe the position as a function of the change in velocity.
Answer:
Due to the rotating effect created due to opposite acting offset forces of the body weight and the normal reaction from the heels.
Explanation:
- We cannot stand on heels with a wall at the back support and then bend over to touch the toes and regain the position back by standing up because we have the center of mass of our body somewhere at the abdominal portion of our body.
- So, while standing on our heels we are giving our body only one point to support and balance itself.
- On bending the center of mass of our body shifts forward and it is now not vertically in line to the direction of the support reaction from the heels because of the wall at the back we cannot bend our knees and move our weight over our heels for gaining the balance. Due to a difference between the these two opposite forces we have a turning effect called moment on the center of mass of our body. This tries to rotate our body in the forward direction about the center of mass of our body.
Answer:
I think your answer is <em><u>Atoms</u></em> .
Explanation:
<em><u>Defination of Atoms?</u></em>
An Atoms is the smallest unit of an element that still has all the properties of that substance.
Answer:
hydrogen bond
Explanation:
Water has atom of oxygen and 2 atoms of hydrogen. The bond is formed between oxygen of one molecule and hydrogen of another molecule. This bond is called hydrogen bond.
It is E=something which leases another something equaling another something
