100
The measurement of an object in relation to time and distance.
What is speed?
100
the formula for calculating speed
What is:
Speed = Distance/Time
100
The formula for calculating acceleration
What is:
Acceleration = Final velocity - Initial velocity/Time
100
Look at the graph showing a car trip. Choose the part of the trip in which the car was traveling at the slowest rate.
What is part iv?
200
A measurement of magnitude or distance and direction.
What is a vector?
200
The formula for velocity
What is Displacement/Time?
200
The measurement of an objects accumulation of speed from one point to another.
What is acceleration?
200
The graph represents this.
What is increasing speed (positive acceleration)?
300
A quickest path between a start position and an end position.
What is Displacement?
300
What is the difference between speed and velocity?
Velocity has a direction.
300
another word for decreasing speed
What is deceleration?
300
The graph represents this.
What is decreasing speed?
400
A measurement of distance or magnitude.
What is a scalar?
400
A man walks 50 meters to his house and then turns and walks halfway back. The whole trip took 3 seconds. What is his average speed?
25 m/s
400
A roller coaster is moving at 25 m/s at the bottom of a hill. Three seconds later it reaches the top of the hill moving at 10 m/s. What is the acceleration of the coaster?
What is -5 m/s2?
400
A ball is thrown vertically into the air. When the graph touches the x-axis, this is happening.
the ball stops rising in the air and begins to fall
500
A point used as a reference in relation to an object's movement
What is a reference point?
500
A kid runs 60 meters to his friend's house and then turns and runs halfway back. The whole trip took 6 seconds. What is his average velocity?
5 m/s
500
If a train going 60 m/s hits the brakes, and it takes the train 1 minute 25 seconds to stop, what is the train’s acceleration?
What is -0.71 m/s2?
500
At what point in the graph is there constant increasing speed
