Virtual Lab: Newton’s Second Law

Document Content and Description Below

Virtual Lab: Newton’s Second Law Purpose: Explore the effect of force and mass on the acceleration of an object. Time: Approximately 50 minutes Question: How do force and mass affect the accelera ... tion of an object? Hypothesis #1: If the force applied to a cart increases, then the acceleration of the cart increases when the mass of the cart is held constant, because force and acceleration are directly proportional to each other according to Newton’s second law. Hypothesis #2: If the mass of a cart increases, then the acceleration of the cart decreases when the force applied to the cart is held constant, because mass and acceleration are inversely proportional to each other according to Newton’s second law. Variables for H1: Independent Variable: force applied to the cart Dependent Variable: acceleration of the cart Constant: mass of the cart Variables for H2: Independent Variable: mass of the cart Dependent Variable: acceleration of the cart Constant: force applied to the cart Summary: This experiment is divided into two parts. For each part, you will use a simulation to measure the position and velocity of a cart as it accelerates along a frictionless surface. A fan on the cart supplies the force needed to move it along the track. For the first part of the experiment, you will examine how the force applied to the cart affects the acceleration of the cart by varying the fan speed on the cart. Varying the fan speed varies the force applied to the cart, causing the [Show More]
