Accelormetres relate to kinematics and especially newtons second law. This is because the accelormeter calculates the acceleration which can be used in the equation F=MA. This equation can be used to calculate the net force of the animal. However you can also use acceleration in kinematics equation. Paired with a GPS system and accelorometer you can calculate velocity, time and distance. This type of information is useful to biologists because then they can see at what velocity did the animal catch its prey or you can see how much force it used.
