Main research question: How do unbalanced forces affect motion?
independent variable: Force
Dependent variable: motion
sub research question 1: how does force affect acceleration?
independent variable: Force
Dependent variable: acceleration
control: Mass
procedure 1: Only use a certain of number weights that are always either on the cart or pulley. Start with 4 weights on the cart and measure the acceleration using the motion detector over 4 trials while moving 1 weight form the cart to the pulley each time.
sub research question 2: how does mass affect acceleration?
independent variable: mass
Dependent variable: acceleration
control: net force
procedure 2:
