Lisa asks…Physics experiment: If i were to roll a marble down a slope, how would i find its acceleration?Also, how would i show the relationship between force, mass and acceleration?
Are there any alternative experiments ?Nancy answers:A=5gsin(theta)/7
you can find the acceleration of the marble by the above formulaNancy asks…How does a quark obtain energy? What is the force behind its positivity?How do they meausure the energy.
Please no formulas. Looking for how a quark obtains energy,
