A science class completed a study on how objects move. All of the following would be considered appropriate when testing the effects of the force of motion on an object EXCEPT- A throwing a baseball B two teams playing tug of war C measuring the size of two marbles D paddling backwards in a boat
In science class, students learned that friction is the resistance to motion when two objects rub together. The students decided to design an experiment at home to compare friction on dry and icy surfaces. Which question is most beneficial for this type of investigation? A Is it faster to sled down an icy hill or down a rough gravel driveway? B What is friction? C What makes ice slippery? D What effect does the height of the hill have on the distance an object travels?
