Motion and Forces
Forces
Forces change motion
A force is a push or a pull
types of forces
size and direction of forces
balanced and unbalanced forces
Forces on moving objects
Newton's first law Relates force and motion
Galileo's thought experiment
Newton's first law
Objects at rest remain at rest and objects in motion remain in motion with the same velocity unless acted on by an unbalanced force
inertia
force and mass determine acceleration
Newton's second law relates force, mass, and acceleration
Newton's second law
force=mass times acceleration
Forces act in pairs
Forces transfer momentum
Forces change the motion of objects in predictable ways
Motion
An object in motion changes position
Position describes the location of an object
Describing a postition
Measuring distance
Motion is a change in position
Describing Motion
Relative motion
The motion of an object can be described and predicted
Speed measures how fast position changes
Position can change at different rates
calculating speed
speed = distance/time
s=speed
d=distance
t=time
Average speed
Distance-time graphs
velocity includes speed and direction
Velocity vs. speed
Acceleration measures how fast velocity changes
Speed and direction change with time
Acceleration can be calculated from velocity and time
Calculating acceleration
Acceleration= final velocity-initial velocity/time
Acceleration over time
Velocity-time graphs
Gravity, Friction and Pressure
Work and energy
Machines
