The force of a moving object is called momentum. the momentum of an object is proportional to its weight and speed. the more momentum it has, the more force it has. so if there were two cars, both the same model, and one of the cars was traveling 30 mph faster than the other, which car has more force?

The car moving at a higher speed, 30mph than the other car

Explanation:

the momentum of a body is a product of mass and velocity. momentum is proportional to mass and also to velocity or speed. this means if the mass increases the momentum increases. Also if speed is increases the momentum is increased. The question refers to two cars of same model which means they have same mass.what would differentiate their momentum is their velocities. The one with the higher speed will have a greater momentum hence a greater force.

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
