100
This unit is the basic metric unit of length.
What is the meter? (m)
100
This is the distance that an object will travel in 15 seconds, if it is moving at 10 m/s.
What is 150 meters? (150 m)
100
This is the formula for speed.
What is SPEED = DISTANCE / TIME?
100
This is the formula to find the amount of time that something was in motion.
What is TIME = DISTANCE / SPEED?
100
This is the formula to find the acceleration of an object.
What is ACCELERATION = (FINAL SPEED - INITIAL SPEED) / TIME?
200
This is a mass equal to 1000g.
What is a kilogram? (kg)
200
This is the distance that a snail will travel in 60 seconds, at a speed of 0.33 cm/s.
What is 20 centimeters? (20 cm)
200
Velocity is described with two things: speed, and this.
What is direction?
200
A car, or another object in motion, will do this if its velocity and acceleration are in opposite directions.
What is decelerate? OR What is slow down? OR What is decrease in velocity?
300
This measurement is the total length that an object travels.
What is distance?
300
This is the total distance traveled by a baseball in one minute, if it is moving at 30 m/s.
What is 1800 meters? (1800 m)
300
This is the average speed of a runner who completes a 200 meter race in 20 seconds.
What is 10 meters per second? (10 m/s)
300
This is the amount of time required to drive 210 miles to Boston, at an average speed of 70 miles per hour.
What is 3 hours? (3 hrs)
300
Given a velocity in meters per second, that changes over a time period measured in seconds, these will be the units of acceleration. (write out the formula to help you)
What are meters per second per second? (m/s/s) OR What are meters per second squared? (m/s2)
400
This measurement is equal to the distance traveled per unit time.
What is speed?
400
This is the total distance driven by a car that travels: 35 miles per hour for 2 hours, then 40 MPH for 3 hours.
What is 190 miles? (190 mi)
400
This is the speed (in km/h) of a bicycle that travels 18,000 meters in 2 hours.
What is 9 kilometers per hour? (9 km/h)
400
This is the time (in minutes) that it takes a runner to complete a 4 km race, at a speed of 10 km/h.
What is 24 minutes? (24 min)
400
A deer is running at 5 m/s. The deer sees a hunter. Over a time of 2 seconds, the deer increases its speed to 13 m/s. Find the deer's acceleration, with careful attention to units.
What is 4 meters per second squared? (4 m/s2)
500
An answer rounded to the nearest hundredth has this many decimal places.
What is two? (2)
500
A moose walks at 6 km/h east for two hours, turns around, then walks 4 km/h west for 30 minutes. Find the moose's total distance from its starting point.
What is 10 kilometers? (10 km)
500
Sally travels for 4 hours on the highway at 65 mph. She then takes a 1 hour break for dinner. When she continues driving, she drives 1 more hour at a speed of 55 mph. Find Sally's average speed.
What is 52.5 miles per hour? (52.5 mph)
500
Arthur walked at a speed of 4 miles per hour, until he was 12 miles from home. He turned around and walked home at a speed of 3 MPH. Find the total time that Arthur spent walking.
What is 7 hours? (7 hrs)
500
A car traveling at 65 km/h quickly slows down to 55 km/h, in only one second. Calculate the acceleration of the car. (positive or negative answers will be accepted. careful with units!)
What is -10 kilometers per hour per second? (-10 km/h/s)
