What is Electric Field
Forces come in two categories: Contact Forces and Non-Contact Forces. Contact Forces are quite usual and customary to us. Electric Force and Gravitational Force are examples of non-contact forces.Non-contact forces or Action-at-a-distance forces requires a more difficult explanation. Example of Non Contact force is that the Moon has a gravitational field around it,and if we get close to the moon,it will pull us down to its surface. Scientists understood why forces acted the way they did when objects touched.The idea that confused them was forces that acted at a distance without touching them.To help them explain what was happening they used the idea of "field". They imagined that there was an area around the object,and anything that entered would feel a force. An electric field describes the area near any electrically charged object. It is also called an electrostatic field.Any other charge that enters the area will feel a force. A normal field is a vector,and is re...
