What can be used to find the direction of a product of two vectors?

Front

The right-hand rule (thumb in direction of A, fingers indirection of B, and palm in direction of new vector)

Back

The Newton is the fundamental unit of force. Whaat units comprise the Newton?

Front

(kg*m)/s²

Back

How should numbers be rounded when using multiplication versus division?

Front

They should be shifted slightly in opposite directions for multiplication and the SAME direction for division!

Back

What should be done when adding vectors?

Front

Tip to tail should be added

Back

At what angle between 0° and 180° do the tangent, cosine, and sine functions have a value of 1?

Front

sin(90°) = 1 cos(0°) = 1 tan(45°) = 1

Back

Differentiate between displacement and distance.

Front

Distance is a scalar quantity while displacement takes the path traveled and is a vector

Back

An angstrom equals how many meters?

Front

10E-10 m

Back

Differentiate between the equations needed to generate the product of two vectors as a scalar quantity. A vector quantity?

Front

|A||B|cosθ for scalar |A||B|sinθ for vector

Back

What is dimensional analysis and how can it be used on the MCAT?

Front

This is looking for patterns with units, and then determining numbers given the relationships between different variables. For example, 1 V = 1 J/C = 1 N*m/C This can then by divided by a number with the formula N/C to get simply m.

Back

What are the two right triangles commonly tested on the MCAT?

Front

A right triangle (90-45-45) and a (30-60-90)

Back

Differentiate between a scalar and vector quantity.

Front

A vector quantity is one with magnitude AND direction while a scalar only has magnitude

Back
