# How to calculate the acceleration force

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.

Hello GG,

Sorry to disappoint you in this your first post: You don't have enough information. Also, your problem description is a bit cryptic: is it the whole story ?
And: 40 km/h is a speed, not an "acceleration speed" -- a term I don't recognize even after many years in physics

At a constant speed the g force on the load is zero.

The mass is 1516 kg. The speed is 40 km/h.

What kind of impact are you talking about? If you want to know the force or the acceleration you need more information, such as the amount of time involved.
