1 Balancing Moments
- seesaw: sube y baja 4
- Perpendicular: At a 90 degree angle to something
- Newton: The unit of measurement of force
- Clockwise: In the same direction as the movement of the hands on a clock
- Counterclockwise: In the opposite direction to the movement of the hands on a clock
Diagram
- a-You have to calculate the moment
- b-The wheel turns more easily when you spin it from near the rim. The distance
M=fd
F=30N
M=fd
Left is 2FI, same result
d=15cm
M=(30) (0.15)=4.5
Right is 2dF, same result
0.15m
M=4.5Nm
2 Making a Scale
- Spring constant: A measure of how stiff or strong a spring is
- Extension: The increase in the length of something
- Elastic: A material able to resume its original shape after being stretched or compressed
- Elastic Limit: The extent to
