This is this impossible question I have to do I dont even know how to start it.
2) The physics equation for Force, F = m*a. (3pt)
Means force (N) is equals to mass (kg) times by acceleration (m/s^2)
...Use an array to store 10 masses and another array to store 10 accelerations.
...Use a loop to calculate and output (document.write) the forces generated.
Sample output: 5(kg) * 10 (m/s^2) = 50 (N)
??????????????????????????????????????????

thats not too hard ! come on i'll help you get started but because its a class I won't give you the full code. (tsdn policies);
so you make an array i would go about it like this -
var masses = [1, 23, 43, 34, 51, 26, 57, 78, 89, 10];
-
var mass = [masses];
-
This is how an array is made
then to pull the data just use -
mass[0][2] this would = 23
-
todo some javascript math i use Math.floor()
Math.floor(Math functions here)
then you need a loop a loop would be made like this for example -
for (i=0; i<10; i++) {
-
dostuff
-
}
-
its i<10 because it starts at 0 so it would be 10 overall when it stops at 9.
document.write is used like this -
-
document.write("hello people!");
-
to add vars to a document.write you do -
document.write("hello people!"+mass[0][i]+" mass!");
-
I need to do a physics equation using Javascript it needs to use the array variable and it needs to contain 10 different equations. I need a equation that looks something like this
5(kg) * 10 (m/s^2) = 50 (N)

You have been given enough information to attempt the problem yourself. If you don't know the basics of javascript, see the tutorial links in the Offsite Links thread at the top of this forum.
Make an attempt and if you get stuck on a particular part, then post again.
Thank you guys This is this code that i used and it worked
<script>
var nAcc = new Array();
nAcc[0] = 3;
nAcc[1] = 4;
nAcc[2] = 5;
nAcc[3] = 6;
nAcc[4] = 7;
nAcc[5] = 8;
nAcc[6] = 9;
nAcc[7] = 10;
nAcc[8] = 11;
nAcc[9] = 12;
var nMass = new Array();
nMass[0] = 3;
nMass[1] = 4;
nMass[2] = 5;
nMass[3] = 6;
nMass[4] = 7;
nMass[5] = 8;
nMass[6] = 9;
nMass[7] = 10;
nMass[8] = 11;
nMass[9] = 12;
var nForce=0;
for (n=0; n<10; n++){
nForce = nAcc[n] * nMass[n];
document.write(nForce + " (N)=" + nMass[n] +"(m/s^2) * " + nAcc[n]+ "kg<br>");
}
</script>

cool good for you.... i had written this code out before i told you how to do it... i made mine with a nested loop for all possibilities. -
<script>
-
function calcForce() {
-
var masses = [2, 4, 5, 12, 1232, 289, 925, 892, 102, 383];
-
var mass = [masses];
-
var accelerations = [20, 12, 44, 218, 12, 33, 11, 22, 23, 78];
-
var acceleration = [accelerations];
-
for (i=0; i<10; i++) {
-
for (b=0; b<10; b++) {
-
document.write(mass[0][i]+"(kg) * "+acceleration[0][b]+"(m/s^2) = "+Math.floor(mass[0][i]*acceleration[0][b])+" (N)<br>");
-
}
-
}
-
}
-
</script>
-
<input type="button" onclick="calcForce()" value="Test">
