Motion and Forces
Gravity, Friction and Pressure
Friction is a force that opposes motion
Friction occurs when surfaces slide against each other
Friction
Forces and Surfaces
Types of Surfeces
Force pressing Sufaces togther
Motion of the Surface
Friction and Heat
Motion through fluids porduses friction
air resistance
Pressure depends on force and area
Pressure desricbes how a force is spread over an area
Pressure acts in all direections
Pressure in fulids depends on dpeath
Pressure in air
Effects on Pressure

Motion
Speed measures how fast position changes
Position can change at different rates
Calculating Speed
Average speed
Distance-Time graphs
Velocity includes speed and direction
Velocity
Vector
An object in motion changes position
Position describes the location of an object
Describing a position

Measuring distance
Velocity verses speed
Motion is a change in postion
Describing motion
Relative motion
Acceleration measures how fast velocity changes
Speed and direction can change with time
acceleration
Acceleration Can be calculated from velocity and time
Calculating acceleration
Acceleration over time
