<span>The shortening velocity refers to the speed of the contraction from the muscle shortening while lifting a load. Maximal shortening velocity is only attained with a minimal load. With a light load, the shortening velocity is at its Maximal shortening velocity. When the weight is heavy, the speed in which the muscle lifts the weight decreases in speed at a slower velocity.</span>
Answer: False
Explanation: A magnetic compass does not point to the geographic north pole. A magnetic compass points to the earth's magnetic poles, which are not the same as earth's geographic poles. Furthermore, the magnetic pole near earth's geographic north pole is actually the south magnetic pole.
Answer: A; True
Explanation: Momentum is known to be a vector quality, and thus has been proven by modern scientists and resulting in this answer being true.

To increase the force required to move an object without change mass is : To increase the acceleration of the object
<h3>Force acting on an object </h3>
Given that Force = Mass * acceleration
An increase in the acceleration of an object in motion will result in a proportional increase in the Force required to move the object becasue force of an object is directly proportional to the acceleration of an object.
Hence we can conclude that To increase the force required to move an object without change mass is To increase the acceleration of the object.
