Physics: Motion in One Dimension
separation from a reference point
separation between two objects
a quantity that only has magnitude or size
a quantity that has both magnitude and direction
magnitude and direction of an object’s change in position (a vector); can be positive or negative
a scalar quantity
ratio of distance traveled to time interval
ratio of change in position to time interval over which change took place
if v is the same for all time intervals
Slope of position-time graph
If position-time graph is a straight line
object is moving at constant velocity.
velocity of an object at a given instant
is slope of the tangent at the time on a position-time graph
ratio of the change in velocity to the time interval over which it occurs.
Slope of velocity-time graph
For uniform acceleration
Velocity-time graph is a straight line
Area under a velocity-time graph
Area under acceleration-time graph
is change in velocity.
Acceleration is constant during upward or downward motion
