Vocabulary
Of an object is the product of its mass and velocity.
Unequal forces pushing in opposite directions
unbalanced forces
What happens when a car slows down and velocity changes?
negative acceleration
What is the formula for calculating acceleration?
A= VF-VI/T
a push or pull
force
Is the distance an object travels per unit of time.
Speed
An object that is neither speeding up nor slowing down travels at a
constant speed
The ___________of an object consists of its speed and direction.
Velocity
What is the formula for calculating speed?
S=D/T
The tendency of an object to resist change in its motion
inertia
Is the rate of changes, the velocity.
Acceleration
A rate of change of the velocity of an object.
acceleration
Displacement must always indicate
direction
What is the formula for calculating time?
T=D/S
The rate change in position at a given point in time.
instantaneous speed
Acceleration toward the center of a curved or circular path.
Centripetal Acceleration
The total distance an object travels divided by the time of travel
average speed
When centripetal acceleration occur, an object
changes direction
What is the formula for calculating speed?
S=D/T
Any change over time
Includes the speed of an object and the direction of its motion.
Velocity
A measure of how far an object has moved
distance
When velocity changes by the same amount over each time interval, acceleration is
constant
What is the formula for calculating time?
T=D/S
A graph with distance on the vertical axis and time on the horizontal axis is called a
distance-time graph
