My 7th grade son has selected a science project which requires to find the impact of two toy cars crashing as part of the larger project. To keep it simple, he will keep one car fixed (i.e. not moving) and the other car crashing into the fixed car at varying speed. I have suggested to use F=ma equation to calculate the force of impact - where mass can be found by weighing the toy car and the acceleration or speed can be found by measuring the distance covered and time it takes to cover the distance by a stop watch assuming the speed is constant. Am I in the right track suggesting this? Is there any other way (simpler) to measure or calculate the impact?

Thanks and Regards
