ACCELERATION Flashcards
- Rate at which velocity changes.
- Change in speed, direction, or both.
- Is a vector quantity
ACCELERATION
Acceleration Formula
(Final velocity - initial velocity)
a = ———————————————-
Time
VELOCITY vs. TIME GRAPH FORMULA
a = Final Velocity - Initial Velocity
————————————–
Final Time - Initial Time
To find the area of the triangle
1/2(Base x Height)
To find the area of the rectangle
Base x Height
To calculate total displacement of an object
Area of Triangle + Area of Rectangle
Area of a Trapezoid
1/2[(Base) x (Height 1 + Height 2)]
Refers to the change in position of an object
Displacement
Elapsed time, or time interval is the time that passes during the chosen period of observation
Time
Quantifies how fast an object moves in a certain direction at the start of the elapsed time
Intial Velocity
Describes how fast an object or body moves at the end of the elapsed time
Final Velocity
Refers to the change in velocity of the object per time interval
Constant Acceleration
Formula for Displacement
d = (initial velocity) (time) + 1/2 (acceleration) (time)²
d = (Vo)(t) + 1/2 x at²
A type of graph that compares how velocity changes over a period of time.
Velocity vs Time Graph
The motion of an object thrown or projected into the air, subject to only the acceleration of gravity
Projectile Motion
A body suspended from a fixed point so that it can swing back and forth under the influence of gravity
Pendulum
Motion of a body where gravity is the only force acting upon it
Free Fall
A specific type of motion in which an object moves along a circular path with a constant speed
Uniform Circular Motion
Uses a horizontal or vertical rod that is twisted and acts as the restoring force when the pendulum is displaced
Simple Pendulum
A more complex pendulum system where the pendulum bob has mass distributed along its length
Compound Pendelum
What is the Angular Speed symbol?
W
