Term
| The speed of light is the _______ __________ for all matter |
|
Definition
|
|
Term
| Two spaceships both traveling close to C toward each other. Is the relative speed over C? |
|
Definition
| No. Space-time for each spaceship differs in such a way that the relative speed is still less than the speed of light. |
|
|
Term

|
Definition
|
|
Term
| Given Einstein’s Relativity Equation for Momentum: p = mv/(1-(v2/c2))1/2 , when V is slow, what is p? |
|
Definition
| p = mv, the same as Newton's |
|
|
Term

|
Definition
|
|
Term
|
Definition
| A true constant, a property of the object at all speeds |
|
|
Term
| The more momentum a high speed particle has, the harder it is to _____________ it. |
|
Definition
|
|
Term
| ___________ is a way of expressing a resistance to change |
|
Definition
|
|
Term
| Einstein’s Relativity Equation for Energy is: E = mc2/(1-(v2/c2))1/2, when V is 0, what is the Energy of an object at rest Eo? |
|
Definition
|
|
Term
| What is the real name for: Eo = mc2? |
|
Definition
|
|
Term
Kinetic Energy is the difference between Total Energy and Rest Energy. So, E = mc2/(1-(v2/c2))1/2 -
What is Eo? |
|
Definition
|
|
Term
| Even at rest, an object has _________ which is locked in its mass. |
|
Definition
|
|
Term
| As the speed of an object approaches the speed of light, both its ____________ and __________ approach infinity, so there is no way the speed of light can be reached. |
|
Definition
|
|
Term
| Can light be brought to rest? |
|
Definition
| No. Light has no rest mass. Light always travels at the same speed, c. |
|
|
Term
| Define: correspondence principle. |
|
Definition
| New and old theories must overlap and agree in areas where old theories have been tested. |
|
|
Term
| Using the Relativistic Rest Mass formula: Eo = mc2, are mass and energy equivalent? |
|
Definition
| Yes. Anything with mass also has energy |
|
|
Term
