Experiment #1

(YOU MUST LOOK AT THIS POST IN PREVIEW MODE)

 Experiment # 1

Inquiry Question : How much torque can my motor create

Hypothesis : A little (0.05 - 0.1N)

Materials: 

Electric Motor x 1

Paper clips x 10

Method :

1. Attach string to motor

2. Add paper clip

3. Turn on motor

4. see if motor stops

5. Repeat steps 2- 4 until motor stops

Force in opposition to motor (0.5 = friction coefficient of wood)

Torque (N) (0.5*m)	Mass (kg)
0.0005	0.001
0.001	0.002
0.0015	0.003
0.002	0.004
0.0025	0.005
0.003	0.006
0.0035	0.007
0.004	0.008
0.0045	0.009
0.005	0.01

                                                                     (Show of torque mass relationship via a graph)

Results : The motor stopped at the force of 0.005 meaning the torque of the motor was in the range of 0.0045 - 0.005 newton-metres

Discussion : The experiment could've been more accurate if I had a more accurate reading of the n/m (such as if I had gone into more in depth weight.) I also could have weighed each paperclip individually or had a more accurate scale to weigh the paperclip as accurately as possible and get the mass of the string. I also could have measured the friction of the wood to metal I was using, rather than using a previously found statistic. For this experiment, i used the formula t = µ*m
