if i dropped the hammer when banging something would my arm hit the object with exactly the same force?

Question

this thought occured to me at work today because i have to hit the sised of metal boxes together then i started thinking of ther angle of the hand swing compared to the hammer head swing

i hope you know what i mean

thank you

Answer 1

I would think it would not be the same velocity,your hand is of course lighter than the hammer

Answer 2

The hammer has extra kinetic energy because it is heavy and you swing it faster than your hand with the handle, which is a lever. The hammer is also hard, so when it hits the object, the force is transferred to a small point on the object which increases the pressure enormously.

Of course, if you swung your hands fast enough, and wore hard gloves, they would work well as hammers.

Answer 3

Your hand isn't traveling at the same speed as the head of the hammer. Plus, the surface area of the head of the hammer is much smaller than your hand. So, even if they were traveling at the same speed toward the object the force would be less for your hand, as it is spread out over a larger distance.

Answer 4

Yes. The hammer only has as much striking force as you impart it with the energy of your swing. The difference is that the small size of the hammer head will transfer more energy to the point of impact than your hand which spread it out a bit.

Answer 5

I think what you need here is kinetic energy. The head of the hammer is more massive than your hand and thus delivers more KE.

Likewise though, the forces would be similarly less due to the decreased mass.

Answer 6

Hi,
The answer is No.
It might feel like the force is the same, but from this equation :
F=MxA
Force = Mass x acceleration.
So with the hammer your arm has more MASS, without it therefore the FORCE of hitting will be a little bit less.
(It will still hurt however)

Answer 7

No. the force is equal to the gravity plus your muscles. The gravity acting on the hammer is greater than your arm because it has more mass, so if u lose the hammer u lose the mass.

Answer 8

It's been a long time since I've done any physics, but I think there's more torque on the hammer since it's a longer distance from the center than where your arm is. I'd have to look it up, but that sounds about it for me.

Answer 9

the force would be different because your arm is a much softer material and has a larger area to distribute the energy... and the length of the hammer handle gives you more leverage and the weight of the hammer head gives more energy as well...

Answer 10

it depends on the force in your hand , the speed which the hammer is moving with , the distance between the hammer initial position and final position , and the angle of attack .
