Mass vs. Force



In class lab:
Ex.
The purpose of this lab was to learn the relationship between force and mass.  My group and I massed various brass cylinders. We learned that the force being exerted on these objects is equal to the mass multiplied by the gravitational constant. Also, to graph the data recorded we used a best fit line. My group and I put the mass of the objects on the y- axis, and the force used on the x- axis. After the experiments were done, were derived the equation "F=MxG" from the graph.

Connection:
Something similar to this can be found in golf. When you strike a golf ball with the head of your club you exert force onto the section of the ball which you hit. Once the ball is hit, the force given off by the ball is equal to its mass multiplied by the gravitational constant     (10 N/kg). To make the ball move further, you need to add more force and speed into your swing. The golf ball eventually falls down because earths gravitational constant is pulling it back to the ground.

  1. Nice work - thank you for summarizing our lab procedures so succinctly. Make sure to include an image of your data, as a reference. Also, the units of the gravitational constant are N/kg. Also, note that the equation we derived from the graph was F=mg.
