Motion and Forces
Motion
Position describes the location of an object.
Position
Describing a Position
Reference Point:
A location to which you compare other locations
Longituted and Latitude
Measuring Distance
Motion is a change in Position
Motion:
The change of position over time
Describing Motion
Relative Motion
You may not think you're movin but an observer could
Einstien's theory of relativity
Speed measures how fast position changes.
Position can change at different rates.
Speed:
measure of how fast something moves or the distance it moves, in a given amount of time
Calculatiing Speed
Must know time and distance
Speed equals distance/time
S=d/t
Average Speed
Distance/time
Distance-Time Graphs
Shows how spped relates time and vice versa
Velocity includes speed and direction.
Velocity:
speed in a specific direction
Vector:
Quantity that has both size and direction
Velocity Versus Speed
Acceleration measures how fast velocity changes.
Speed and direction can change with time.
Acceleration:
Measure of how quickly the velocity is changing
What is the relationship between velocity and acceleration?
Accelerationin the Same Direction as Motion
Acceleration in the Opposite Direction of Motion
Acceleration at a Right Angle to Motion
How does acceleration affect velocity?
Acceleration can be calculated from velocity and time.
Acceleration=(final velocity-initial velocity)/time
a=v final - v initial / t
Forces
Gravity, Friction, and Pressure
Work and Energy
Machines
