Definitions
Total Distance traveled divided by the total time it took to travel that distance
Average Speed
Speed at a specific point in time
Instantaneous Speed
What is the definition of distance or can you explain it to me?
Total length of a path an object takes
What is velocity?
Speed and Direction
What are 3 ways an object can accelerate?
Slowing down
Speeding up
Changing direction
Process of changing position
Motion
3 motions that can be shown on a distance - time graph.
What do they look like?
Slowing down
Stopping
Speeding up
What is the definition of displacement or can you explain it?
Quickest way from point A to point B.
Difference between the initial position and the the final position.
Explain how velocity can change.
The speed changes
Direction changes
Or both
Can you give me an example of something that is accelerating
Some object moving that changes its speed or direction
Difference between initial and and final position of an object.
Displacement
What are 3 things you need to describe an objects location?
Reference point, distance, direction
What must change if the reference point changes?
Distance and Direction
On a distance time graph if Line A is steeper than Line B what does that mean which line is going faster?
Line A is going faster
What is the acceleration formula?
V(f)-V(i) divided by T
Rate of change of position in which same distance is traveled each second.
Constant speed
Who was in Mr. Woelber's slideshow at the beginning of the year that wasn't apart of his family?
DARTH VADER
What are the measurements of an objects motion?
Distance and Displacement
Define speed and tell me how it is determined
Speed is a measure of the distance an object travels per unit of time
D/T
Describe to me what leaving an intersection looks like. Your answer should include the velocity and which way it is accelerating.
Acceleration increases in the same direction as that in which the car is moving
An objects distance and direction from a reference point.
Position
What are the 5 ways motion can be described?
Position, Velocity, Instantaneous speed, acceleration, and average speed.
Define Motion and explain how to determine whether motion has occurred.
Motion: The process of changing position.
Has occurred: Distance from object and reference point changes.
Explain what a speed-time graph indicates about an object’s motion.
how speed changes over time
What does a distance time graph and a speed time graph look like when an object is speeding up?
Distance time graph looks like a half U
Speed time graph is a straight line.
