chapter 2 Flashcards
what is translational motion?
Change of position between 2 points
exp of curvilinear
x-y axis
what is kinematics?
Description of motion without regard to its causes
what is dynamics?
Study of physical concept and motion
what is position vector?
A vector starting from reference point to a given point
What is distance?
length measured along the actual path taken
what is displacement?
change in position vector.
What is average speed?
total distance travelled divided by total time
What is average velocity?
Rate of change of displacement
What is instantaneous velocity?
average velocity during the time interval approaches zero.
what is acceleration?
Change of velocity in unit time
What is average acceleration?
rate at which velocity changes.
What is instantaneous acceleration?
limit of average acceleration as, delta t approches zero
What is uniform acceleration?
A particle is moving with the same acceleration at every instant of time.
