General Science Chapter 5 Work and machines General Science Chapter 5

What is Work? Labor Work Cleaning Cooking Laundry Homework Moving the lawn -

Measuring Work 1) Measure force 2) Measure distance Work = - - = Joules

Measuring Work Example Maria pushed her bike for 10 meters at a force of 2 newtons. How much work did she do? Work = -

Force, Distance and Work - Work = - Force = - Distance = -

Simple Machines - Levers Pulleys Inclined plane Screws Wedge Wheel and Axle

Levers - Effort force- Resistance force- the force applied to the lever by the object 3 types First-Class Second Class Third Class

Types of levers:

Mechanical Advantage Simple machines - The machine Mechanical advantage = the number of times the machine multiplies your force Machine force/your force = mechanical advantage

Other Simple Machines Pulley- Inclined Plane- a.k.a. a ramp Screw-

More Simple Machines Wedge Wheel and Axle- used in cars and door knobs
