How does the mass affect the amount of force needed to make an object move?
Hypotheisis: We think that the higher the mass is, the harder it will be to move the object.

IV: Mass of the object. DV: Force applied.

Here is a screen shot of the graphs of the force applied to the fridge... As you could probably see, the fridge did not move at all because it was too heavy and there was alot of friction and other counter forces acting apon it to make it not move.

Here is a screen shot of the graphs of the force applied to the crate... As you can see, you needed less force to move the crate than the fridge. The mass of the crate is 300kg vs the 400kg fridge.

Here is a screen shot of the force applied to the sleeping dog... As you can see, the sleeping dog was easier to move than both the fridge and the crate. It is 25 kg.

Here is a screen shot of the force applied to the textbook... As you can see, the textbook moved very easily with very little force applied to it. This was because it is on 10kg in mass.

Was the hypothesis supported or disproved? Our hypthesis was supported because the objects with the higher masses required more force to be able to move. The objects with the smaller masses needed little force to be able to move.

Table Of the Experiment:



Conclusion: We concluded that as mass increases so does the force needed to move the object. The smaller the mass, the less amount of force needed to move the object. We think this is because with higher masses there are higher counter forces acting on the object causing it to be harder to move. Counter forces are forces like friction, gravity, and lift. In this case only friction would really affect the objects movment.
