o Well-established theories are physical laws

▪ i.e. Newtown’s Laws of Motion

Kinematics

• Description of motion

• Motion in one dimension

o x at time t

• Displacement

o Vector change in x from t1 to t2

• Average velocity

• Instantaneous velocity

Acceleration

• Curvature of the x(t) graph

• Average acceleration

• Instantaneous acceleration
