descibe the advanages of plotting data in graph form
Eric, I'm not sure what you need, but if it's Physics tuition (or Math)try Khan Academy. Hundreds of short vids. Hope Jiskha don't mind this post.

The moon is about 240.000 miles from earth. What is this distance written as a whole number multiplied by a power of ten
Force = Massx acceleration. Find the accel using v=u+at, solving for a. v is the final velocity (0); u is the initial (9.4), t is time (0.2) Then x by 110 kg. to get the force in Newtons.
B is between A and C. Solve for x, if AB=2x+6, BC=4x-3, and AC=5x+12
V^2=u^2+2as. v= the final velocity; u=the initial velocity (9.2 m/s; a is accel and s is distance (more accutately, displacement). Solve for v.
The ball goes 120m in time t. t, or fall time, is sqrt of 2h/g, both given. 120/t gives the x component of velocity in m/s.
Picture a right angled triangle with one side AB being 25 x 125 metres long to the west; the other side BC being 19 x 66 metres long to the south. The displacement is the length of the hypotenuse AC; the direction being between 180 degrees and west. Sketch it out, then do the ...
Assuming the 'passing the window'part means 0.10s to go from the top to the bottom of the window... Then the veocity will be 1.18/0.1, so 11.8m/s. Accel will be that of 'g', so 9.8 m/s^2; and the initial velocity was 0 m/s. Use v^2=u^2+2as Solve for s, which wi...
Initial velocity is given, final velocity is given, and the time is given. Using these, rearrange v=u+at to solve for a. The ball is slower after the bounce, so what sign will the acceleration be?
