Hi Guys & Girls, Hereby, I am a newbie in this forum and I have a question which is regarding how to calculate the deceleration gravity force. Below is the information that I have, 1. Acceleration Speed = 40 km/hr 2. Tonne of the load on truck = 1,516 kg So, is there any of the formulation to calculate the gravity force of the impact to the load? in "g" forces.
