Module 2: One-Dimensional Motion Equations and Free Fall Flashcards
What is the formula to… determine velocity from displacement and change in time?
v = Δx/Δt
What is the formula to… determine acceleration from change in velocity and change in time?
a = Δv/Δt
What is the formula to… determine final velocity using initial velocity, acceleration, and time?
v = vo + at
What is the formula to… relate velocity to displacement and acceleration?
v^2 = vo^2 + 2a * Δx
What is the formula to… determine displacement for an object using the graph: velocity-vs-time?
Δx = vot + 1/2 at^2
Objects falling near the surface of the earth experience a constant acceleration of ___________________ straight down. (Abbreviation ‘g’)
Objects falling near the surface of the earth experience a constant acceleration of **9.8 m/sec2 (32 feet/sec2)* straight down. (Abbreviation ‘g’)
The acceleration due to gravity is independent of the _________________________________…
The acceleration due to gravity is independent of the nature of the object experiencing free fall, as long as the object has mass… in other words gravity isn’t subjective as to the force it exerts upon objects in free fall.
When an object is thrown upward in the presence of gravity, the object will reach its maximum height when __________________. In addition, when it returns to the height from which it was thrown, its velocity will be _________________________
When an object is thrown upward in the presence of gravity, the object will reach its maximum height when the object’s velocity equals zero. In addition, when it returns to the height from which it was thrown, its velocity will be equal to and opposite of it’s initial velocity.
What are the qualities of an object that affect its terminal velocity?
Qualities that affect the terminal velocity of an object…
- Weight
- Shape
- Orientation
Define Free fall…
Free fall: The motion of an object when it is falling soles under the influence of gravity
