conversion and Units
100
The rate at which an object moves a certain distance.
What is speed?
100

The speed of a jogger that ran 350 meters in 70 seconds.

What is 5 m/s?

100

What are the units for aceceleration?

meters per second per second

m/s2

100

Draw a line showing constant velocity on the graph on the whiteboard.

any straight line

100

how many millimeters in 25 centimeters?

250 milimeters

200
How fast an object moves over a certain distance in a direction.
What is velocity?
200

The distance an object travels if the velocity is 25 m/s and the time is 20 seconds.

What is 500 meters?

200

What are the 3 different examples of acceleration?


Speeding up, slowing down, or changing directions.

200

Draw a line showing acceleration on the position time graph

any curved line

200

What is the basic unit of distance measurement scientists prefer to use?

the meter

300
velocity = distance / time
What is the equation for velocity?
300

The time it takes an object to travel 200 meters at a velocity of 33.33 m/s.

What is 6 seconds?

300

what 3 parts of the car can we call accelerators?

gas pedal
break pedal
steering wheel

300

draw a line showing a person walking, stopping for 2 minutes and then walking at the same original speed

slope, flat, slope

300

what does the SI in SI units stand for?

Systeme international or international system of units

400
The equation used to solve for distance in the speed/velocity equation.
What is distance = velocity x time?
400

The velocity of an object that travels 23 meters in 18 seconds.

What is 1.28 m/s?

400

A.) Give one way to change speed and not direction.

B.) Give one way to change direction and not speed.

A. hit the gas or breaks, blow on the marble from behind,

B. bank around a corner, travel in a circle, 

400

What would need to be on the left y axis for this graph to show acceleration?

speed, not distance

400
How many Kilometers is 20 meters?

0.02km

500

why do you need a reference point when trying to measure speed?

speed is relative, if you are both in a car your speed from each other is different than your speed from the side of the road.

500

How far does an object travel in 20 minutes if its speed is 120 miles per hour

distance = speed x time

in 1 hour that = 120 miles

20 minutes = 1/3 of an hour.

1/3 of 120 = 40 miles.

500

What is the formula to solve for acceleration?

(final speed - starting speed) / time

500

Draw a graph showing an object accelerating at a constant rate for 3 seconds, moving at a constant speed for 3 seconds and then suddenly stopping.

left side shows speed, bottom is time.

increasing slope, flat line, straight vertical line

500

how many mm is 1 km?

1,000,000mm

(one million millimeters = 1 km)
