Measurement of upward force exerted by a human on a vertical jump?

AI Thread Summary
The discussion focuses on measuring the upward force exerted by a human during a vertical jump, essential for creating a realistic physics-based platform game. Key factors influencing this force include the jumper's mass, the gravitational environment, and the jump's acceleration, with Newton's second law (F=ma) being crucial for calculations. The conversation suggests practical experimentation, such as jumping on a scale, to measure force directly. Additionally, there is a mention of academic resources for further research on vertical ground reaction forces. Accurate physics modeling is emphasized as vital for enhancing gameplay realism.

Hi,

I'm doing some research on developing a physics-based platform game and I want to see how the gameplay will feel if the environment and physics were made to scale as realistically as possible.

Since one of the core features of a 2D platformer is jumping, I need some figures on how much force is actually exerted when a human jumps vertically.

Are there any resources regarding this?

Thanks!

Well, first of all it depends on 1) the mass (in Kg) of the person jumping, 2) the gravitational potential that the person is jumping through (is he on the Earth, the moon, Mars?), and 3) the acceleration of the person due to the jump. After you've identified those parameters, I think all your going to need is Newton's handy old F=ma to get your answer. As far a resource related to gaming algorithms, I am unaware of any, but I'd imagine they exist "pre-fabbed" somewhere, its a common feature in many games even though I'm not a gamer.
 
It's not going to be much of a platformer if the character can't jump 2-3 times his height. A human can't even jump 5 feet in the air from standing, but Super Mario jumps 3 times his own height.

Anyway, why don't you stand on a scale and jump to see how much force you exert on the ground.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
