CHAPTER 2
Describing Motion:Kinematics in One Dimension
2.5 Motion at Constant Acceleration
s=ut+(1/2)at^2
v=u^2+2a
v=u+at
v=v+u/2
2.2 Average Velocity
sAvg = ΔD/Δt
D = distance, meters (m)
t = time,sec (s)
2.9 Graphical Analysis and Numerical Integration
2.7 Freely Falling Objects
due to earth's gravity (9.81m/^2)
at maximun height, v=0
fall with constant acceleration
ignore the air resistence when do the calculation
2.6 Solving Problem
2.8 VAriable Acceleration; Integral Calculus
2.3 Intantaneous Velocity
The instantaneous speed always equal to the magnitude of the instantaneous velocity;it only equal the average velocity is constant
2.1 Reference Frames and Displacement
Any measurement of position , distance or speed must be bade with respect to a reference frame
2.4 Acceleration
a=change in velocity/time
