Document Summary
The purpose of this experiment is to determine the relationship between force and acceleration and mass and acceleration in accordance with newton"s 2nd. According to newton"s second law of motion fnet a if mass remains constant, where fnet represents the force acting on the cart (n) and a represents acceleration of the cart in (m/s2). Also a 1/m when force remains constant, where m represents the mass. As a result the acceleration versus force graph will yield a positive sloping linear graph, where as the acceleration versus 1/mass graph will yield an exponential function. Observations: observations of acceleration of toy cart moving on horizontal surface. Experiment 1 the effect of force on acceleration. Independent variable: force: dependent variable: acceleration, constants: mass of system. This is only a slight difference and does not dramatically effect the acceleration versus force graph. a= m1g/ m2 + m1.
