Motion & Forces
Forces Transfer momentum
Objects in motion have momentum
Momentum can be transferred from one object to another
Momentum is conserved
Two types of collisions
Momentum and Newtons Third law
Pressure depends on force and area
Pressure describes how a force is spread over an area
Pressure acts in all directions in fluids
Pressure in fluids depends on depth
Pressure in Air
Changing elevation
Changing Density
Effects on pressure
Pressure in Water
Fluids can exert a force on objects
Fluids can exert an upward force on objects
Buoyancy
Density and Buoyancy
The motion of a fluid affects its pressure
Bernoulli's Principle
Applying Bernoullis Principle
Forces can be treansmitted through fluids
Pascals Principle
Hydraulics
Energy is transferred when work is done

Motion
Describing a postion
Measuring Distance
Motion is a change in Position
Describing a motion
Relative motion
Speed measures how fast position changes (FORCES)
Position can change at different rates
Calculating speed

Balanced forces
Action and Reaction
Newtons three laws describe and predict motion
Friction is a force that opposes motion
Friction occurs when surfaces slide against each other
Forces and Surfaces
Types of Surfaces
Motion of the Surfaces
Force pressing the surfaces together
Friction and Heat
Motion through fluids produces friction
Work is the use of force to move an object
Force is necessary to do work
Force, Motion, and Work
Calculating work
Objects that are moving can do work
Power is the rate at which work is done
Power can be calculated from work and time
