Motion: Acceleration and Velocity - Coggle Diagram
Motion: Acceleration and Velocity
Acceleration
Change in velocity/change in time
Acceleration increases when falling because of gravity
Acceleration decreases going up and is 0 at its highest point
when velocity is constant, acceleration equals 0.
When an object accelerates, it...Must change its velocity
Might only change direction, only speed up, or only speed.
Instantaneous velocity
When it's falling: 10m/s
The velocities you collect
-10m/s when it's going up (going against force of gravity). Will be 0 at the top and then start going faster.
It is the velocity at a certain point, NOT the average.
(See Blue for more details)
Average Velocity
Final velocity+Original velocity/2
Can also use all data and divide by however many there is to average the whole thing.
Another way is to take the first and last and divide by two.
Final velocity and initial velocity
Use them to find instantaneous velocity.
Pf-Po OVER Tf-To
Displacement
Take the AVG velocity = DELTA X/DIFFERENCE IN TIME. Multiply by difference in time.
Need measurements for average velocity and time.
When plotting positions, Start at 0, then use first position with velocity at 1. Then, start adding the displacements to get the next positions.
Units to use
Velocity: m/s
Time: Seconds
Acceleration is m/s/s OR m/s^2
Disaplcement: Meters
Position: Meters
