Guide QUESTIONS AND CORRECT
ANSWERS
Dot Product - CORRECT ANSWERS multiply parallel vectors then add
for SCALAR answer=56 Joules
Cross Product - CORRECT ANSWERS use matrix to multiple
perpendicular vectors to get a vector answer 3Nmi-6Nmj+3Nmk
average velocity - CORRECT ANSWERS average velocity is the slope
of the secant line
First kinematics equation (constant acceleration)
no displacment - CORRECT ANSWERS This is also average
acceleration (slope of the second line of a velocity vs time graph)
Second kinematics equation (constant acceleration)
no final velocity - CORRECT ANSWERS most often used for projectile
motion
Third kinematics equation (constant acceleration
no time - CORRECT ANSWERS
Fourth Kinematics Equation (constant acceleration)
no acceleration - CORRECT ANSWERS
Instantaneous velocity - CORRECT ANSWERS slope of the Tangent line
, Power rule forward (multiply by exponent then subtract one)
Finding Position given velocity versus time equation - CORRECT ANSWERS
Area of velocity vs time plus initial position
power rule backwards (add one and then divide by exponent) + initial condition
instantaneous acceleration - CORRECT ANSWERS Slope of the Tangent
line
power rule forwards (multiply by exponent then subtract one)
2nd derivative of position as a function of time
