Name: Solutions Physics 106 Prelab Questions on Force Mass and Acceleration 1. In today’s experiment, you will be studying the relationship between force, mass and acceleration. At the beginning of the lab, you will be asked to measure the force needed to keep the puck stationary at the four different locations shown in the figure below. If the θ is and the mass of puck is 1 kg, please estimate the magnitude of this force at each location. (Use ) ° 30 2 / 10 s m g = The force needed to keep the puck stationary at the four different locations should be the same. N mg F 5 ) 30 sin( 10 1 ) sin( = × × = = ° 2. In the force on a stationary puck part of the experiment, you will replace the 2

All of the variables in the right side of the equation are constants except for h, which can be changed by inserting the different wooden blocks. So F is proportional to the h. Given that when tilt is 0, F is 0, we have 4 2 10 3 15 F = = So F=20 N and m=2 kg....
