QuestionAnswer
DisplacementThe change in an object's position.
Vector quantityA physical measurement that contains directional information
Scalar quantityA physical measurement that does not contain directional information
VelocityThe time rate of change of an object's position
SpeedThe time rate of change of the distance traveled by an object
Instantaneous VelocityThe velocity of an object at one moment in time.
Average VelocityThe velocity of an object over an extended period of time.
AccelerationThe time rate of change of an object's velocity.
2 conditions that must be met in order to use equations for one dimensional motion1. Acceleration must be constant. 2. Motion must be in one direction.
9.8m/sec^2The gravitational acceleration of objects near the earth's surface.
The more that air resistance affects an object,...The smaller its terminal velocity will be.
The weight, shape, and orientation of an object affectterminal velocity
Free fallthe motion of an object when it is falling solely under the influence of gravity.
Terminal velocitythe velocity a falling object has when, due to air resistance, its acceleration is reduced to zero. This is the maximum velocity a falling object subject to air resistance can achieve.
