A student has begun training for tryouts for the track team by running two miles through her neighborhood every day. Part of the run is a very steep hill. One day, the

student is running down the hill at a very quick pace when she notices a dog lying in the middle of her path. To avoid hitting the dog, she tries to stop but has difficulty. With effort, she is able to stop right before running into to the dog.

Explain why it was so difficult for the student to stop. In your response, be sure to include:

 the role of Newton’s first law in making it difficult for the student to stop.

 the correct use of the term inertia.

 why some objects in motion have more inertia than others.

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?
