Momentum
Potpourri
100
True or False: All matter in the universe is constantly in motion.
What is true?
100
It is the distance an object travels in a unit of time.
What is speed?
100
It is the change in velocity divided by the time it takes for the change to occur.
What is acceleration?
100
It measures the quantity of matter.
What is mass?
100
It is the tendency of an object to resist a change in its motion.
What is inertia?
200
The measurement of length between two points.
What is distance?
200
It is the Speed Equation.
What is distance over time? s=d/t
200
True or false. If a car is accelerating, its speed must be increasing.
What is false? (acceleration is also slowing down or changing direction)
200
It is the measure of how hard it is to stop an object, and it depends on the object's mass and velocity.
What is momentum?
200
This type of graph can be used to compare the speeds of objects.
What is a distance-time graph?
300
To determine of something changes position, you must have a _____________ of _____________
What is a point of reference?
300
It is the total distance traveled by total time taken.
What is average speed?
300
Acceleration is in the direction that an object is moving when an object does this.
What is speeds up?
300
What does the letter "p" symbolize in the Momentum Equation?
What is momentum?
300
It is the speed of an object and the direction of its motion.
What is velocity?
400
True or False. Distance traveled and displacement are always equal.
What is false?
400
It is the SI unit for speed.
What is meters per second? (m/s)
400
Calculate the acceleration of a bus whose speed changes from 6 m/s to 12 m/s in 3 seconds.
What is 2 m/s (squared)? a = final speed - initial speed/ time
400
It is what happens to momentum in a collision.
What is the momentum is transferred?
400
The speed of an object at one instant of time is called this.
What is instantaneous speed?
500
It is the direction and difference between starting and ending points; overall change of position
What is displacement?
500
A passenger train travels from Boston to New York, a distance of 350 km, in 3.5 h. What is the train's speed?
What is 100 km/h? 350km/3.5h = 100 km/h
500
This is the type of acceleration that occurs when objects slow down.
What is negative acceleration?
500
The total momentum of a group of objects remains constant unless outside forces act on the group.
What is the Law of Conservation of Momentum?
500
On a speed-time graph, a horizontal line represents this.
