What Hooke’s Law states is that small deformations of an object, the displacement, or size of the deformation is directly proportional to deforming force or load2. In basic terms the amount of force you pull is proportional to amount the object stretches or retracts. F represents force measured in Newton’s and is derived from the slingshot when the rubber is released from its final displacement. x represents the length of the total displacement of the rubber band before and after its release. k called the “spring constant” is the variable we are trying to find as well is the total of the stress made on the object.

Observation/ Research: Boyle’s Law As Robert Boyle stated “Pressure and Volume are inversely related. To add more, temperature and moles are constant.” (Boyle). So, if Pressure increases, then the volume decreases or the other way around. This is Boyle’s Law. According to this law, P x V = k, where k is a constant.
We know that F=ma where the mass is the cart plus the weights with friction considered, and we know that weight=mass x gravitational field strength. So, we use w-fric=ma instead of F=ma, where the force is substituted by the weight minus the friction. This can be rearranged to isolate a as such: a = (1/m)w - (1/m)fric and because w in this case represents F, it can be written as a= (1/m)F - (1/m)fric. This

The driving force for a phase change is the minimization of free energy and causing material or heat transfer are balanced at equilibrium. The equilibrium phase is always
Chemical reactions transform bond energy into heat or work. Enthalpy of reaction (Hrxn) is the term used for the change in heat as a reaction is carried out at constant pressure. It is a state function as it only depends on the final and initial conditions during the change of state. If Hrxn < 0, the system releases heat and is therefore an exothermic reaction. On the other hand, if Hrxn > 0, the system absorbs heat.
There exists, however, a distinguished scale where one would expect that typical quantum-gravity effects can never be neglected. This scale is found if one combines the gravitational constant (G), the speed of light (c), and the quantum of action (ħ) into units of length, time, mass (and energy).These are called the Plank unit.
When a force is applied it relates to both the amount of force and the amount of time for which it is applied. What were Newton’s 3 Laws of motion? The First law of Motion for Newton states “A body in motion will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force.” It also states that things can’t start, stop, or change direction by themselves. The First Law of Motion is known as inertia. The Second Law of Motion states “the force acting on an object is equal to the mass of that object times the acceleration.
