Situation B Click on the \"Friction" tab at the top. Again, set the ramp angle to zero degree. Now double the mass of the crate using the appropriate slider or entering the value. Predict the value of the applied force necessary to get the crate moving. Apply the force. What is the actual value needed to move the block? How does it compare to your prediction? With the doubled mass, change to a different acceleration due to gravity, such as that on the Moon or on Jupiter. Enter the new value of g here: . Again, make a prediction of the value of the applied force necessary to get the crate moving. What is the actual value needed to move the block? How does it compare to your prediction
