Ok I've been trying to figure this out for some time now
We all know the formula F=ma
now acceleration is measured a=(v-v0)/t
now if there was an object in motion (lets say we measured the speed of a vehicle moving in a straight line at a constant speed of 10m/s over 30 seconds) this gives us v=10m/s and v0=10m/s and t=30s
so a=(15-15)/30=0
a=0
lets say the object weight 2000kg
F=(200)(0)=0
that gives us a F force of 0N
so if this hypothetical vehicle is traveling at 15m/s it has a Force of 0N. But if it smashes into a wall that wall suffers damage due to applied force. Where does this force come from? Using Newton's equation the car has no force but we know from practicality that a car going 15m/s has a lot of force to exhert on a stationary object
Is there another formula for F force if an object is at a constant velocity?
