Observing Friction

Procedure

1. Lay a bar of soap, a flat eraser, and a key side by side on one end of a hard-sided notebook. 2. At a constant rate, slowly lift the end of the notebook with objects on it. Note the order in

which the objects start sliding. Record your observations in the table.

Data and Observations

Bar of Soap

Eraser

Key

Analysis

1. For which object was static friction the greatest? For which object was it the smallest? Explain, based on your observations.

2. Which object slid the fastest? Which slid the slowest? Explain why there is a difference in speed?

3. How could you increase and decrease the amount of friction between the two materials?

Measuring Force Pairs

Procedure

1. Work in pairs. Each person needs a spring scale. 2. Hook the two scales together. Each person should pull back on a scale. Record the two

readings in the table below. Pull harder and record the two readings. 3. Continue to pull on both scales, but let the scales move toward one person. Do the readings

change? 4. Try to pull in such a way that the two scales have different readings.

Data and Observations

Set-up

Scale 1

Scale 2

First pull

both partners pull

Second pull

both partners pull harder

Third pull

scales closer to one person

Fourth pull

Fifth pull

Analysis

1. What can you conclude about the pair of forces in each situation?

2. Explain how this experiment demonstrates Newton's third law.

Balloon Races

Lab Preview

Directions: Answer these questions before you begin the Lab.

1. What does Newton's third law of motion state?

2. What will you use to make a path for your rocket?

The motion of a rocket lifting off the launch pad is determined by Newton's laws of motion. Here you will make a balloon rocket that is powered by escaping air.

Real-World Question

How do Newton's laws of motion explain the motion of balloon rockets?

Materials

balloons drinking straws meterstick

string tape stopwatch

*clock

*Alternate materials

Goals

Measure the speed of a balloon rocket. Describe how Newton's laws explain a rocket's motion.

Safety Precautions

Procedure

1. Make a rocket path by threading a string through a drinking straw. Run the string across the classroom and fasten at both ends.

2. Blow up a balloon and hold it tightly at the end to prevent air from escaping. Tape the balloon to the straw on the string.

3. Release the balloon so it moves along the string. Measure the distance the balloon travels and the time it takes.

4. Repeat steps 2 and 3 with different balloons.

Analyze Your Data

1. Compare and contrast the distances traveled. Which rocket went the greatest distance?

2. Calculate the average speed for each rocket. Compare and contrast them. Which rocket has the greatest average speed?

Conclude and Apply

1. Infer which aspects of these rockets made them travel far or fast.

2. Draw a diagram on a separate sheet of paper showing all the forces acting on a balloon rocket.

3. Use Newton's laws of motion to explain the motion of a balloon rocket from launch until it comes to a stop.

Communicating Your Data

Discuss with classmates which balloon rocket traveled the farthest. Why? For more help, refer to the Science Skill Handbook.
