Unit 7
Vocab
Distance: The change or displacement of a position of an objects
Acceleration: The change in velocity over a certain period of time
Vector: the direction of movement from point A to point B
Motion: the changing position of an object over a period of time
Velocity: the change in the position of an object over a certain period of time
Velocity
Instantaneous velocity: the position of the object at a certain period of time
the average velocity: is the average of the velocity between 2 intervals.
Equation to find velocity: final velocity=original velocity/ final time-original time
Typically given by 10m/sec
Accelaration
Velocity is negative or decreases on the way up because the force of gravity is working against it, when it stops at its highest point the velocity is 0. When going down the velocity increases as the force of gravity is working WITH IT.
Equation to find average velocity: V final + V original/ 2
acceleration increases on the way down because of gravity
when an object accelerates its always because of gravity
to find the acceleration we have to use 2 average velocities
difference: velocity is the change in position over the change in time while acceleration is the change in velocity over a period of time
V final- VO/ T
Extra notes
you can stop the data when it hits the ground because objects can not go further in real life
