As she worked to adapt her program to her specific business Jamie found that she could now effectively use the help feature of the program, which allowed her to make a lot of progress.

The alternating accelerations of the skull and the inertia of the brain combine to cause impacts on opposing sides of the brain during a coup contrecoup injury.

So applying the rule for division, the final result should have the same number of significant figures as the least number in the division, which in this case is the three significant figures in 393 mm.

An engineer performing an inspection on the previous structure measures 45 m from beneath the center of gravity of the block to the point where the structure contacts the ground. She then measures the distance to the beneath the center of gravity of the arm to be 95 m.

Often W is used to abbreviate weight, but is also used because it reminds us that an object’s weight and the force of gravity on the object are the same thing. We usually try to make the length of the arrows proportional to how big the forces are, in which case the arrows can be called vectors.

Metacognition can help you recognize when you don’t yet have enough information to make a good decision, so it might significantly improve your learning and help you avoid barriers to success, both in school and in life.

Remembering that the stress applied to a material is the applied force divided by the cross-sectional area, we understand that large forces associated with high accelerations can lead directly to injury level stress on tissues.
