Motion
A quantity that has both magnitude and direction
Vector
A vector expression of the displacement that an object or particle undergoes with respect to time
Velocity
The magnitude or size of displacement between two positions.
Distance
A vector quantity that is defined as the rate at which an object changes its velocity.
Acceleration
State of a body that moves freely in any manner in the presence of gravity.
Free Fall
Used to describe the position of an object in space
Coordinate System
The time rate at which an object is moving along a path
Speed
The location of an object at any given time
Position
The rate of change of velocity, or the change in velocity per unit time.
Average Acceleration
An object falls from a high building and hits the ground in 9.0 seconds, ignoring air resistance, how tall is the building
396.9m
Represents the position, velocity, and acceleration of an object at various clock readings.
Motion Map
An object must have a constant speed in a constant direction.
Constant Velocity
The change in position of an object.
Displacement
When an object continues to speed up or slow down at the same rate
Constant Acceleration
A rock is dropped from a garage roof from rest. The roof is 8.0 m from the ground. determine how long it takes the rock to hit the ground (round to the hundredths place).
1.28s
The motion of an object in which the object travels in a straight line
Uniform Motion
A type of graph that compares how velocity changes over a period of time.
Velocity Vs Time Graph
This shows how far an object has traveled from its starting position at any given time since it started moving.
Position Vs Time Graph
The ratio of change in velocity during a given time interval such that the time interval goes to zero.
Instantaneous Acceleration
Wile-E-Coyote drops a bowling ball off a cliff to try to catch the roadrunner. The cliff is 132m high. what is the velocity of the bowling ball before impact ( round to the tenths place)?
-50.9 m/s
If the speed of an object moving along a straight line keeps changing
Non-Uniform Motion
A physical quantity that is completely described by its magnitude.
Scalar
The center of a coordinate axis, defined as being the coordinate 0 in all axes.
Origin
A force that exists among all material objects in the universe.
Gravity
If an object fall from a high building, ignoring air resistance what will its velocity be after 8.5 seconds of falling?
-83.3 m/s
