Can someone explain the normal force? where does it come from? ...?
Vilka [71]
<span>The normal force is the support force exerted upon an object which is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. The normal force in itseñf comes from the third law of Newton as a reactive force</span>

ki77a [65]
The answer is <em>Compressional Stress
</em>

In geology, stress<span> is the force per unit area that is placed on a rock. ... This is called confining </span>stress<span>. Compression squeezes rocks together, </span>causing<span> rocks to fold or fracture (break). Compression is the most common </span>stress<span> at </span>convergent plate boundaries<span>.

A 2 kg blob of putty moving at 3 m/s slams into a 3 kg blob of putty at rest. Which blob has the most momentum prior to the coll
Ray Of Light [21]

initial momentum of 2 kg blob is given as

P_1 = m_1v_1

here we have

m_1 = 2kg

v_1 = 3m/s

P_1 = 3(2) = 6 kg m/s

initial momentum of 3 kg blob is given as

P_2 = m_2v_2

here we have

m_2 = 3kg

v_2 = 0m/s

P_2 = 3(0) = 0 kg m/s

So initially 2 kg Blob has most momentum before they collide
