Phyics Flashcards
Work Function
Minimum energy required to remove electron from metal surface
Threshold Frequency
Minimum frequency photon must have to liberate an electron
Elastic Collision
Momentum & kinetic energy are conserved
Inelastic Collision
Momentum is conserved but kinetic energy is not conserved
EMF
Amount of energy transferred from chemical energy to electrical energy per unit charge
Internal Resistance
Resistance of the materials from the source
Elastic Limit
The point at which the solid is permanently stretched and will not return back to its original length
Proportionality of Resistance to Length and Area of a wire
R ∝ L/A
Tensile Stress
Force per unit cross-sectional area
Tensile Strain
Ratio of extension per unit length
Elastic Limit
The maximum amount that a material can be stretched and still return to its original length when the force is removed
What Roles do Exchange Particles Play
- Transfer Energy
- Transfer Momentum
- Transfer Force
- (Sometimes) Transfers Charge
What Property Defines a Hadron
Particles experience the strong interaction
Displacement
Distance and direction of vibrating particle from equilibrium position
Amplitude
Maximum displacement of a vibrating particle from equilibrium position
