net force‚ mass and acceleration Hypothesis: Since Newton’s second law of motion states that the acceleration of an object is directly proportional to the total force acting upon that object‚ we can assume that the more mass being pulled down on the cart the greater the acceleration of it will be and therefore the greater its net force will be.

proportionality of acceleration and net force if the mass of the body is constant and to verify the inverse proportionality of acceleration and mass if the net force is constant. It is now clearly explained and proven that Newton’s second law of motion is true. By experiments‚ the law is proved. All data produced results parallel to what Newton states. We can say that the acceleration is directly proportional to the net force if the mass of the body is constant. The acceleration increases as the

Sierman Lab Report: Experiment #7 Group #4 October 16th‚ 2012 Forces on a Pulley System A. Statement of the Problem The purpose of this lab was to address the following questions: how does the acceleration of a pulley system depend on the mass of the driving objects? And how does the acceleration of a pulley system depend on the mass of the driven object? To achieve this‚ a dynamic track was set up with a string attached to a cart. The string was part of a pulley system (the pulley was at the

Relationship Involving Acceleration‚ Net Force‚ and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force‚ mass‚ and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass‚ then the acceleration would increase‚ because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force‚ then the acceleration would increase

2.6.1 Draw a vector diagram to show that the acceleration of a particle moving with uniform speed in a circle is directed toward the centre of the circle. Review of basic kinematics: If the acceleration and velocity of an object are parallel (or anti-parallel) then the object’s speed will increase (decrease). If the acceleration and velocity of an object are perpendicular then only the direction of the velocity will change and the speed (i.e. the magnitude of the velocity) will remain constant.

with the cart’s acceleration. The total mass of the cart is easy to vary by adding masses. Using these tools‚ you can determine how the net force on the cart‚ its mass‚ and its acceleration are related. This relationship is Newton’s second law of motion.

Assessment Andy Tang Research Question In this internal assessment‚ I am given a cantilever to find the physical properties of it. I decide to investigate the relationship between the force I act on one side of the cantilever and the maximum acceleration the tail can reach. This experiment will be also showing the elasticity of the cantilever. Since I pull down one side of it and fixed the other side‚ when I cut the string‚ it will bounce up and down until all the internal energy is depleted.
