Diferentiate between pushing and pulling forces?
Pushing and Pulling differ like Positive and Negative directions.
When upward is positive then acceleration sign is?
Positive if the acceleration is also upwards directed, and if you are considering a one dimensional space where you thus only have upwards and downwards as directions. Otherwise you need to more information before you able to answer this question.
Why if total momentum is zero but kinetic energy is not equal to zero?
This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.
How do their directions compare with the direction of the force that acts on a positive test charge in the same region?
694321 +411+456+ 0012314566 2115+4+636.254= 1.231463579e11
Why can velocity be positive or negitave?
Velocity can be a positive or a negative because velocity is a vector, which means it is also affected by direction. This that if one car is going +10 m/s and another is travelling at -10 m/s, this means that they are travelling the same speed in opposite directions.
What is velocitys symbol?
Velocity's' symbol is represented by a simple: "V".
Compared to Jupiter and Saturn Venus and Mars have greater?
Orbital velocitys
What is velocitys formula?
There are a few: v=d/t v=v0+at are the most basic
What is velocitys position time graph?
The velocity position time graph is rightward. This can change at anytime.
Are you sure that the light and dark red lines means positive?
Follow the directions on the test box. If the directions say the reading is positive, yes you can be sure the test is correct.
Is acceleration the slope of the velocitys vs the time graph?
Yes, acceleration is the slope of a velocity versus time graph.
Why positive displacement are called positive?
Because it has been decided that the right and upwards directions in a plane are the positive directions and the left and downwards are negative. Originally, the decisions were arbitrary but conventionally agreed (in the same sort of way that North is usually shown at the top of a map). Any displacement in a positive direction is called a positive displacement.
What are the cartesian base vectors in mathematics?
They are unit vectors in the positive directions of the x and y axes.
What terms blank and blank can be useful when giving opposite directions from a reference point?
Positive and negative
How are the directions of motions indicated?
The directions of motion can be indicated by vector rays; indicating geographic directions such as north, south, east, west; positive or negative signs indicating upward and downward, north and south, east and west; and angles.
Can an electric current move in two directions at once?
Not simultaneously. Though it can alternate. If you mean in one circuit there can be alternative directions in which the current can move. Electrical currents go from the negative to the positive since electron (electricity is a lot of electrons) is negative so is directed to the positive.
Diferentiate between pushing and pulling forces?
Pushing and Pulling differ like Positive and Negative directions.
