Journal Question 05 Dec 2012 Take a half-sheet of paper from the

front bench and answer today’s journal question.

Describe, using your science vocabulary, something you learned about designing roller coasters. Each vocabulary word that you correctly use in your paragraph is worth one point.

Speed

Directions: Calculate Speed for the following:

DistanceTime = Speed Meters/Seconds

1) 50 kilometers in 2 hours2) A fox ran 200 meters in 25 seconds while chasing after a rabbit. How fast was the fox running?

Answers

1.) 25 kmph (kilometers per hour)

2.) 8 mps (meters per second)

Reference Point

If you were standing at the bus stop, name some reference points you could use to know that the bus is moving.

Answer

Describe the motion of the squirrel at points A, B, and C.

A

B

C

Answer

At point A, the squirrel is moving slower than point C.

At point B, the squirrel has stopped. At point C, the squirrel is moving the

fastest.

Describe the motion between points A and B, B and C , C and

D.

Answers

Between points A and B the object is accelerating (speeding up).

Between points B and C, the object is moving at a steady speed.

Between points C and D, the object is slowing down.

ForcesA B

1) What will happen if the forces between person A and B remain balanced?2) What will happen if one person exerts more force than the other?3) How do friction and gravity effect the people tugging?

Answers

1) The forces are balanced on the rope. There will be no change in motion.

2) The rope will move in the direction of the person exerting more force.

3) Lots of answer to this question….discuss with a partner and be prepared to share.

Mass vs. Weight

You are the driver of The Magic School Bus. You are going to take our class on a trip. We need to bring our lunches along with us.

1) What will happen to the mass of our lunches if we take them Jupiter?

2) What will happen to the weight of our lunches when we are in space?

Answers

1) Nothing! The mass of our lunches will stay the same.

2) Our lunches will be weightless in space, but the mass will remain the same.
