kinematics

Question 1

kinematics

Answer 1

the form, pattern, or sequencing of movement with respect to time
-things to can see on film
Variables:
-Distance, displacement
-speed, velocity
-acceleration
-step length, width
-times that events occur

Question 2

linear kinematics

Answer 2

distance vs displacement
-distance=length of path traveled (scalar)
-displacement (d)= final change in position from starting to ending point (vector)

Question 3

speed

Answer 3

how fast an object is moving, nothing about the direction of movement (scalar)
distance/time
(m/s) (miles/Hr)

Question 4

pace

Answer 4

reciprocal of speed
-time/distance

Question 5

velocity (magnitude and direction)

Answer 5

involves direction as well as speed
-sign on velocity tells direction they are going
-displacement/ change in time

Question 6

acceleration (m/s^2)

Answer 6

the rate of change of velocity
-can be positive or negative
change in velocity/change in time

Question 7

if you are speeding up in the negative direction you have

Answer 7

negative acceleration
