Choose two points, such as two doorways, and mark each with a small piece of masking tape. Measure the distance between the two points. Use a watch, clock, or timer that indicates seconds to time yourself walking from one mark to the other. Analysis 1. Calculate your average speed in each case. Predict how long it would take you to walk m slowly, at your normal speed, and quickly.
Use masking tape to lay a course on the floor. Mark a starting point and place marks along a straight path at 10 cm, 40 cm, 90 cm, cm, and cm from the start. Clap a steady beat. On the first beat, the person walking the course should be at the starting point. On the second beat, the walker should be on the first mark, and so on. Describe what happens to your speed as you move along the course.
Infer what would happen if the course were extended farther. Repeat step 2, starting at the other end. Are you still accelerating? How many large marbles do you need for this lab? How many small marbles? A collision occurs when a baseball bat hits a baseball, or a tennis racket hits a tennis ball. What would happen if you hit a baseball with a table-tennis paddle, or a table-tennis ball with a baseball bat? How do the masses of colliding objects change the results of collisions?
Real-World Question How does changing the size and number of marbles in a collision affect the collision? Determine how the speeds after a collision depend on the masses of the colliding objects. Safety Precautions Procedure 1. Tape the metersticks next to each other, slightly farther apart than the width of the large marbles. This limits the motion of the marbles to nearly a straight line. Record your observations in the table in the Data and Observations section.
Place a small target marble in the center of the track formed by the metersticks. Place another small marble at one end of the track. Flick the small marble toward the target marble. Describe the collision. Repeat step 2, replacing the two small marbles with the two large marbles. Repeat step 2, replacing the small shooter marble with a large marble.
Repeat step 2, replacing the small target marble with a large marble. Repeat step 2, replacing the small target marble with four small marbles that are touching. Place two small marbles at opposite ends of the metersticks. Shoot the marbles toward each other and describe the collision. Place two large marbles at opposite ends of the metersticks. Place a small marble and a large marble at opposite ends of the metersticks.
Describe In which collisions did the shooter marble change direction? How did the mass of what is spouse or common-law partner in canada class target marble compare with the shooter marble in these collisions? Explain how momentum was conserved in these collisions. Communicating Your Data Make a chart showing your results.
You might want to make before-and-after sketches, with short arrows to show slow movement and long arrows to show fast movement. Which safety symbol is associated with this lab? What should be the topic of your hypothesis? Imagine that you are a car designer. How can you create an attractive, fast car that is safe? When a car crashes, the passengers have inertia that can keep them moving. Real-World Question Test Your Hypothesis How can you protect the passengers from stops caused by sudden head-on impacts?
Form a Hypothesis Develop a hypothesis about how to design a car to deliver a plastic egg quickly and safely though a race course and a crash at the end. Design a safe car that will protect a plastic egg from the effects of inertia when the car crashes. Possible Materials insulated foam meat trays or fast food trays insulated foam cups straws, narrow and wide straight pins tape plastic eggs 1. Be sure your group has agreed on the hypothesis statement.
