Module 1: Motion in One Dimension Flashcards
Define Displacement
The change in an object’s position.
Define Vector Quantity
A physical measurement that contains directional information
Define Scalar Quantity
A physical measurement that does NOT contain direction information
Velocity
The time rate of change of an object’s position
Speed
The time rate of change of the distance traveled by an object
Instantaneous velocity
The velocity of an object at one moment in time
Average velocity
The velocity of an object over an extended period of time
Acceleration
The time rate of change of an object’s velocity
What is the slope of a position-versus-time curve?
The slope of a position-versus-time curve is the velocity
What is the acceleration formula?
a = Δv / Δt v = velocity t = time
The slope of a velocity-versus-time curve is the __________?
The slope of a velocity-versus-time curve is the acceleration.
If the velocity is zero, does the acceleration have to be zero?
No, absolutely not.
If acceleration is zero, the velocity ________________?
If acceleration is zero, the velocity does not have to be zero.
What is the formula for velocity?
v = Δx / Δt x = position t = time
