Force is mass times accelaration Question inside

HI all

We know that Force = Mass * Acceleration

An object moving at constant velocity will have zero acceleration. So when it impact an object or a person, a force is felt. Equation above suggests that force is zero.

Please explain why this equation fails for this case, and a mathematical formula for deriving the force that is actually felt.

Thats becasue when you hit something, you decelerate.

The deceleration is generally very high if you hit a brick wall, hence a large force is felt.

Therefore the mathematical formula for the force you feel is....

F=m*a

Exactly, when you hit something, your acceleration is no longer zero.

You'll learn more about collisions when you get into momentum.
