What is the rate of change in velocity?
acceleration

3. A change in position in a particular direction.
displacement
A plot of the acceleration of an object as a function of time.
Acceleration Time Graph
Acceleration which does not change during an interval of time.
constant acceleration

4. Velocity which does not change during an interval of time.
constant velocity
The length moved between two points.
distance
The velocity at which an object starts at the beginning of a time interval.
initial velocity

5. The value of a quantity at a particular instant of time, such as position, velocity, or acceleration.
Instantaneous
The study of how motion occurs.
Kinematics
The zero location in a coordinate system.
reference point

6. The ratio of distance to time.
speed
What two centuries marked the beginning of our modern understanding of motion?
16th and 17th
What two scientists are given credit for the study of motion?
Galileo and Newton

7. What two parts is mechanics divided?
Kinematics and Dynamics
Objects that move without rotating exhibit ___________ motion.
translational
An ___________ particle is a mathematical point with no spatial dimensions.
idealized

8. The description of how objects move.
Kinematics
The study of force and why objects move as they do.
Dynamics
This is a measure of how far an object is from its starting point.
displacement

9. The sum of the magnitudes of the lengths that an object has traveled.
distance
A quantity that has both magnitude and direction.
A vector
A quantity with magnitude only.
A scalar

10. Average velocity is defined in terms of ____________, not distance.

Why is 100 = 1?
We know that 1000/1000 = 1.
1000 = 103
103 / 103 = = 100
Therefore, 100 must be equal to 1.

distance

16. What is the area beneath an acceleration time graph?
velocity
