6. Collect data: Select the DESCRIPTION tab. On the SIMULATION pane, turn on Show mass. This lists the total mass of the cart. Each fan exerts a force of 4.0 newtons (N). One newton is the force required to accelerate a 1-kg object at a rate of 1 m/s2. For each combination, record the total force, total mass, and acceleration. On the last column, multiply the mass (m) and acceleration (a). Load # fans on Force Mass Acceleration m . a 2 fans, 0 blocks 2 8 1 fan, 2 blocks 4 3 fans, 1 block 3 12 What do you notice about the force and the product of mass and acceleration, ma? . Because they are connected, you can treat both masses as part of the same system. 7. Draw conclusions: Newton's second law states that force is equal to mass times acceleration: F= ma. This law can be rearranged as a = F / m, or a = F : m. How does this experiment demonstrate Newton's second law? Because you can use the data tables to work out the equations
