Fd-Fd=0
If I jump forwards (due to the electromagnetic structure of the molecules of my body), the binding energy of my constituent molecules is increased, while I produce radiation as well as kinetic energy directed at the floor. Therefore, all other things equal, I add an impluse to the Earth equal to the integral of (Force * time). Some of the kinetic energy impacts onto the Earth becomes radiation. But the radiation has a (momentum*speed of light) which we can interpret as a radiative energy, as an analog to kinetic energy (since they are transformable to each other). The change in pressure*volume would therefore correspond to my change in kinetic energy+the change in my radiation + the change in the Earth's kinetic energy + the change in Earth's radiation... Would it not?
Would then change in pressure*volume correspond to 2*Fd, or while disregarding radiative loss, twice of the change in my kinetic energy, thus, mv^2?
Andrew Mason said:I lost you when you started talking about pressure*volume. Are you talking about the atmosphere? How does kinetic energy and radiation affect PV?
Also, are you suggesting that the kinetic energy of the Earth is equal to the kinetic energy of the person jumping?
Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.
According to Newton's first law, an object in motion will stay in motion unless acted upon by an external force. This means that an object with kinetic energy will continue to move at a constant velocity unless a force is applied to change its motion.
A common example is a ball rolling on a flat surface. The ball will continue rolling at a constant speed unless it encounters an external force, such as friction or hitting an obstacle. Another example is a car coasting on a flat road. The car will continue moving at a constant speed unless the brakes are applied.
According to Newton's first law, an object's mass does not affect its response to an external force. However, an object with a larger mass will have a greater inertia, meaning it will be more resistant to changes in its motion.
Yes, Newton's first law can be applied to objects in space. In the vacuum of space, where there is no air resistance, an object in motion will continue moving at a constant velocity unless acted upon by an external force, such as gravity or the thrust of a rocket.
