Motion

Acceleration

the rate of change of the velocity

indicates any change in the velocity vector

To find it:

Reading graphs

Position

States where an object is located

x-, y-, and z-coordinates

Point of reference in relation to origin

Displacement

Definition:The change of the position vector

How to find it: The final position vector minus the initial position vector

Remember: does not necessarily equal the total distance traveled

Velocity

depends on displacement and time interval

Average velocity

Instantaneous velocity

Reading Graphs

Newton's second law

rate of change of the velocity is proportional to the net force and inversely proportional to the mass of th object

net force is constant the acceleration is also constant

Applying to problems

Constant net force

equations

Visualization

Motion diagrams

Free Fall

No forces act on an object other than the gravitation force that makes the object fall

Air resistance

massive objects are harder to accelerate

More mass=more inertia

the acceleration of an object in free fall is the vector of "g" regardless of the object's mass

9.80 meters per second squared

Motion of projectiles

an object moves in the xy-[plane with constant acceleration then both a of x and a of y are constant

Projectiles

Angle of elevation

Trajectory

Apparent Weight

the feeling of "weightless"

elevator example

Air resistance

Drag force
