3.2 Weight, Gravity, and Friction
How does increasing the mass of the car affect its acceleration?
2
Key points Gravity Weight Definition Formula Friction Cause Types
3
Gravity Force that pulls every mass toward every other mass.
Downward force Depends on mass Less on Mars More on Earth 9.8 m/sec2
4
Weight Force created by gravity on an object Changes with location
Formula If you have… And you need… Fw = mg Mass and gravity Weight m = Fw / g Weight and gravity Mass g = Fw / m Weight and mass Gravity
5
Friction Forces caused by motion between objects (microscopic hills and valleys) Work against motion that produces them Reduces acceleration All machines have Types: Air Viscous Sliding Rolling
