Virtual Lab: Newton’s Second LawPurpose: 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 acceleration 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
