Kinematics

Question 1

kinematics

Answer 1

the study of description of the spatial and temporal characteristics of motion without regard to causative forces

Question 2

linear motion

Answer 2

motion along an axis in which all points of the system move at the same time, in the same direction, and the same distance with respect to the defined reference frame despite their location on the system

Question 3

rectilinear motion

Answer 3

linear path is straight

Question 4

curvilinear motion

Answer 4

linear path is curved

Question 5

angular motion

Answer 5

motion when all the points on a body or object move in circle about the same fixed central line or axis

Question 6

general motion

Answer 6

combination of linear and angular motion

Question 7

linear distance

Answer 7

the total length of the path traveled by the system of interest
indicates magnitude

Question 8

linear displacement

Answer 8

the change in linear position of the system in a straight line
in a specified direction from the initial position to the final position

Question 9

speed

Answer 9

scalar rate of motion

Question 10

velocity

Answer 10

vector rate of motion

Question 11

average speed/velocity

Answer 11

rate of motion over a time interval

Question 12

instantaneous speed/velocity

Answer 12

rate of motion at one given instant in time

Question 13

peak rate of motion

Answer 13

maximum rate of motion achieved

Question 14

acceleration

Answer 14

change in magnitude and/or direction of the velocity vector with respect to time

Question 15

average acceleration

Answer 15

rate of change in velocity over a time interval

Question 16

instantaneous acceleration

Answer 16

rate of change in velocity at one specific instant in time

Question 17

peka acceleration

Answer 17

maximal acceleration achieved

Question 18

if acceleration and velocity are in the same direction

Answer 18

faster

Question 19

if acceleration and velocity are opposite

Answer 19

slower

Question 20

if acceleration =0

Answer 20

velocity f=velocity i

Question 21

if acceleration = +

Answer 21

velocity f > velocity i

Question 22

if acceleration = -

Answer 22

velocity f< velocity i
