PHET Net Force Lab

Explore forces and motion with the PHET Net Force Lab simulation!

Net Force Simulation Step 1: Choose Net Force.Step 2: Make sure that Sum of Forces and Values is checked. It’s in the upper right hand corner.Step 3: Put all of the people available on each side of the cart so it looks like this. How many newtons of force (N) are pointing to the left and to the right? B. What is the sum of the forces under these conditions? C. Press the Go button. Describe the motion of the cart. D. This is an example of balanced forces. What do you think the term balanced forces means? Step 4:Press the orange Return button. Step 5: Reset the people so it looks like this. E. How many newtons of force (N) are pointing to the left and to the right? F. What is the sum of the forces under these conditions? Which way is the green arrow pointing? G. Press the Go button. Describe the motion of the cart. H. This is an example of unbalanced forces. What do you think the term unbalanced forces means?
