Kinematics in One Dimension
Reference Frames and Displacement
Displacement
how far object from starting point
△x=x2-x1
Distance
measured along the actual path
Average Velocity :
Average speed= distance/time
Average velocity=displacement/time
Instantaneous velocity
Tangent to the curve of distance vs time
dx/dt
Acceleration
Average acceleration= change of velocity/time
Acceleration zero when velocity constant
Instantaneous acc=dv/dt
Motion at constant acceleration
Freely Falling Objects
Ignore air resistance, all objects fall with same acceleration
Object is zero velocity at highest point
Variable acceleration; Integral Calculus
dx = v dt
Integration is applied
dv = a dt
