Force, Mass and Acceleration

Purpose: - What relationship exists between the acceleration of an object, its mass, and the net force applied?

Hypothesis: -
i need help to write Hypothesis
can u help me

Read this introduction (what textbook are you using?), and then tell us what the relationship is between force F, mass m, and acceleration a.

Spell out Newton's law -- what is the equation relating F, m and a?

Once you have that equation, what would you hypothesize about a, if you knew the mass of an object and the force applied to it? How would you go about testing this hypothesis?

I Have That Result
Can U Check
Is That Right?
PLZ CHECK LAST ONE MASS*ACCLERATION
IS THAT RIGHT?

Parts of it do not look correct. First, what's a cart? Are you using carts of different masses or different numbers of carts or something to check F=ma experimentally?

Also, I don't know what the [F] is at the top of each column. The letter "F" is usually reserved for force, and units are usually put in square brackets []. You can leave the units in the round parenthesis () if you want, but what is meant by [F]?

is my mass*acceleration colum right or wrong?

Hard to tell, but the numbers looked cooked up, instead of being the results of an experiment. Is this just a thought experimen? What exactly is the problem statement? Please be specific.
