## Study Notes

### Electric Charge and Electric Field

• The fundamental property of matter that gives rise to electric force is electric charge.
• The SI unit of electric charge is the coulomb (C).

### Electric Field Due to a Positive Charge

• The direction of the electric field at a point due to a positive charge is radially outward from the charge.
• The electric field due to a positive charge is radial and outward, and its magnitude decreases with distance from the charge.

### Electric Potential Energy

• When two like charges are brought closer, their electric potential energy increases.

### Electric Field and Electric Potential

• Electric field and electric potential are related, with the electric field being the negative gradient of the electric potential.
