Speed
Velocity
Acceleration
What formula would this go with?
Hodge Podge
100
What is the formula for speed?
Speed = Distance / Time
100
What is the formula for velocity?
Velocity = Distance (displacement) / Time with a direction
100
The rate of change of velocity.
What is acceleration
100
What formula is m/s an example unit?
speed or average speed
100
What can we find with a distance vs time graph?
average speed of an object
200
How is speed different from velocity?
velocity needs a direction
200
What is the velocity of an object that is moving 6 meters in 2 seconds east?
3 m/s east
200
How can we tell if an object is accelerating? Name the 3 ways.
speeding up (increasing speed) slowing down (decelerating) changing direction (turning)
200
What is km/hr South a possible unit for?
Velocity
200
What goes on the x-axis?
x-axis = time on both the distance vs. time AND the speed vs. time graphs!
300
Name units often used for expressing speed.
miles/hours (mi/hr), meters/second (m/s), kilometers/hour (km/hr)
300
Distance = 20 meters Time = 4 seconds Direction = south What is the velocity of this object?
5 m/s south
300
Can an object accelerate if it is moving at a constant speed?
Yes, it can change direction (ex: carousel moving at a constant speed).
300
Which of our formulas must have a direction in order to be complete?
velocity
300
The change in position of an object.
What is displacement
400
A porcupine moved toward a pond at a speed of 5 m/s. It took him 8 seconds. What was the distance he traveled?
40 meters
400
An object travels 25 meters in 2 seconds east. What is it's velocity?
12.5 m/s east (must include direction!)
400
It is the general term for negative acceleration.
What is deceleration
400
Name units often used for expressing velocity.
Km/hr, m/s, mi/hr - with a direction! Must have a direction with unit!
400
The distance that an object travels in 15 s at a speed of 10 m/s.
What is 150 m?
500
The speed of a car that travels 400 miles in 5 hours?
What is 80 miles per hour.
500
Calculate the velocity of a mountain climber if that climber is moving northeast at a pace of 3 km in 1.5 hours?
2 km/hr northeast
500
How would you describe negative acceleration? You must use the word "velocity".
What is a decrease in velocity over time (slowing down)
500
How many seconds will it take for a satellite to travel 450 km at a rate of 120 m/s? What formula would you use to solve this problem?
Time = distance / speed
500
What two variables must you have in order to calculate speed?
What is distance and time
