Physics final

Potential Energy

Energy that is stored in an object or substance

Gravitational Potential Energy

Energy stored in an object that is elevated

Elastic Potential Energy

Energy stored in an object that can stretch or compress

Chemical Potential Energy

Energy stored in foods

Electric potential Energy

The energy that is needed to move a charge against an electric field

conservative force

A _____________ exists when the work done by that force on an object is independent of the object's path.

Conservative force

A force that conserves mechanically

V= PE/q

Formula for electric potential Energy

Voltage

Potential Difference another term

PEgrav.=mgh

Gravitational potential energy formula

Voltage/ potential difference

It is the invisible force that is pushing the electric current to make it flow in conducting loop

Energy is the one that is stored in power source and the voltage is the one who pushes the electric current

Differentiate Voltage and Energy

yes

Alessandro volta

Volts named after

The flow of charges in a circuit starts from negative to positive terminal

Describe the flow of charges in a circuit

Electric Field

The region around the charged object

Voltage

the potential energy per unit charge

VAB=Ed

Electric potential in a uniform electric Field formula

Because charge moves from higher potential energy to lower potential energy

What is the reason there is a negative charge in the formula -VAB=ED

Electric field lines

A series of lines drawn from a point charge representing the magnitude and direction of force exerted by that charge.

True

Electric Field is a Vector Quantity. True or false?

begins on positive charges and ends on a negative charge

number of field lines is proportional to the magnitude of the charge

The strength of the field is proportional to the closeness of the field lines

The direction of the electric field is tangent to the field line at any point in space

Field line never cross

Properties of electric field

Conductor

A substance or material that allows electricity to flow through itConductor

It allows free charges to move about within it.

Translational velocity

any object that is conducting a motion in a straight path or curved path

Rotational velocity

velocity of an object that is going in a cyclic path

Net force

Sum of all forces acting in an object

Translational and rotational velocity must be 0

The netforce of an object must equal to 0

Criteria of an object to be considered a static equilibrium

Static equilibrium

State of an object that is at rest

Δ V = Δ PE / q

Potential Difference/ Voltage formula

Electrostatic Equilibrium

When there is no net motion of charge within a conductor
