$$\Delta v=\frac{w}{q'}$$  

$$E=\frac{F}{q'}$$  

$$\Delta v=Ed$$  

$$C=\frac{q}{\Delta V}$$  

gain electric potential energy

lose electric potential energy

increases as the the vertical distance between interacting masses increase

decreasses as the masses increase

depend on the speed of the interacting masses

depends on whether the intercting masses are at rest or in motion

The ability to gain kinetic energy

the ability to store potential energy

the ability to lose potential energy

the transfer energy from one object to another

W= $$q'\times d$$  

$$w=F\times d$$  

$$w=m\times d$$  

$$w=F\times g$$
