Irregular Bones
An irregular bone is one that does not have any easily characterized shape and therefore does not fit any other classification. These bones tend to have more complex shapes, like the vertebrae that support the spinal cord and protect it from compressive forces. Many facial bones, particularly the ones containing sinuses, are classified as irregular bones.
Sesamoid Bones
A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed. These bones form in tendons (the sheaths of tissue that connect bones to muscles) where a great deal of pressure is generated in a joint. The sesamoid bones protect tendons by helping them overcome compressive forces. Sesamoid bones vary in number and placement from person to person but are typically found in tendons associated with the feet, hands, and knees. The patellae (singular = patella) are the only sesamoid bones found in common with every person. [link] reviews bone classifications with their associated features, functions, and examples.

<em>Answer: the force applied on an object will make the object move fast if a lot of force is applied and slow if less force is applied. and based on the direction the force is coming from the object will go to.</em>
<em />
Explanation:
force...
The object would have a centripetal acceleration <em>a</em> of
<em>a</em> = (12 m/s)² / (0.7 m) ≈ 205.714 m/s²
so that the required tension in the string would be
<em>T</em> = (0.5 kg) <em>a</em> ≈ 102.857 N ≈ 100 N
(rounding to 1 significant digit)
1).
Time = (distance) / (speed)
Time = (1000 meters) / (331 m/s)
<em>Time = 3.02 seconds</em>
2).
Acceleration = (change in speed) / (time for the change)
Change in speed = (second speed) - (first speed)
Change in speed = (50 m/s) - (20 m/s) = 30 m/s
Acceleration = (30 m/s) / (5 seconds)
<em>Acceleration = 6 m/s²</em>
