Motion and Position
A change in an object's position relative to a reference point is...
What is motion?
This is the distance an object travels per unit of time.
What is speed?
This includes the speed of an object and the direction of its motion.
What is velocity?
This is the product of an object's mass and velocity.
What is momentum?
This is the rate of change of velocity.
What is acceleration?
A frame of reference is a __________ _______ in which the position of the object is measured.
What is a coordinate system?
The formula for calculating speed is this.
What is: speed = distance over time?
True or false: It is possible for two objects to have the same speed but different velocities.
What is true?
This is the unit for measuring momentum.
What is kg.m/s?
A change in velocity can be either a change in _______ or in ________.
What are speed and direction?
The x and y axis are drawn ___________ to each other and ___________ at the reference point.
What are: perpendicular and intersect?
When your speed is changing, and you have calculated it, it is actually considered this.
What is an average speed?
Earth's tectonic plates are moving by _____ per year.
What is centimeters?
The equation for calculating momentum is this.
What is p=mv?
Changing the direction of your acceleration is the same thing as this.
What is slowing down?
This is the distance and direction of an object's change in position.
What is displacement?
When you are traveling a particular speed and you record what it says on your speedometer at that moment, you are determining this.
What is instantaneous speed?
This is the reason that objects moving past each other, at the same speed, seem to be moving faster than objects moving together at the same speed.
What is a moving reference point?
This has larger momentum: (car or truck) because of its _________.
What is a truck and mass?
Acceleration toward the center of a curved or circular path is called this.
What is centripetal acceleration?
To calculate displacements in the same direction you _________, in opposite directions you ____________, and if they are not the same or opposite directions you.....
What are: add, subtract, cannot be directly added together?
On a speed-distance-time graph, you can determine the fastest one by this.
What is the slope of the line?
A baseball has the momentum of 6.0 kg.m/s south and a mass of 0.15 kg. This is the baseball's velocity.
What is 40 m/s? v=p/m
Two objects traveling at the same speed and are the same size, the one with larger _________ will have larger momentum.
What is velocity?
When you are aiming at a bulls eye, this is the direction you should aim because...
What is up because of gravity pulling it downward?
