How does an electric field get stronger? |
|
Definition
The electric force decreases as the distance increases.
Soooo.... I guess the electric force increases as the distance decreases? |
|
|
Term
What results when an object has more negative charge than positive charge? |
|
Definition
When an object has more negative charge than positive charge it creates an unbalanced charge and it requires an electrical discharge (the process of an unbalanced electric charge becoming balanced) |
|
|

Term
What is the formula for momentum? |
|
Definition
Momentum= mass x velocity
or
p=m x v |
|
|
Term
What is the formula for force? |
|
Definition
force= mass x acceleration |
|
|
Term
________ is the rate of change of position in which the same distance is traveled each second. |
|
Definition
|
|
Term
|
Definition
The total distance traveled divided by the time taken to travel that distance |
|
|
Term
_______ is a measure of change in velocity during a period of time. |
|
Definition
|
|
Term
What is the formula for acceleration? |
|
Definition
A= Vf - Vi over t
(in m/s2) |
|
|
Term
|
Definition
Speed and direction of a moving object |
|
|
Term
___________ is a measure of the change in velocity during a period of time. |
|
Definition
|
|
Term
Does velocity change when moving in a straight line? |
|
Definition
It can. Velocity is affected by speed and/or direction, so if the speed changes the velocity will change, even if moving in a straight line. |
|
|
Term
What is the formula for average speed? |
|
Definition
Average speed= distance over time |
|
|
Term
________ is the difference between the initial position and the final position of and object.
