Analysis of the effects of the force of an object on its acceleration in a systemAbstract: In an air-track, the acceleration of the cart changes with a change in the hanging mass. This is based on Newton's second law that states: F = m*a. We observed the relationship between the force of the hanging bobs and the resulting acceleration of the cart. We performed 6 sets of trials with a different number of bobs hanging, and had 4 runs per set. This way, we could change the force acting on the cart, and note the acceleration. We made sure the total mass remains constant by hanging the desired number of bobs on the string, and attaching the rest of the bobs to the cart. The acceleration was measured using a photo gate and necessary computer software. From these results, the slope of the force vs. acceleration graph was linear and positive. Therefore, the acceleration of the cart increased as the force of the hanging mass increased. Experimental Design:Group IGroup IIGroup IIIHypothesisAcceleration of the mass on the cart is directly related to the force of the hanging mass.The hanging mass value will affect the acceleration of the system.The acceleration of the block will remain unchanged due to constant force. When mass increases, acceleration will increase.Independent VariableForce due to bobsNumber of bobsNumber of bobsDependent VariableAccelerationAccelerationAccelerationControl variablesMass of 1 bob = 4.84 g, Mass of gold cart = 0.159 gMass of syste ...
