• How does the type of shoe affect the amount of force required to pull it?

• How does a spring scale work?

• How much force is required to pull the high heel shoe?

When designing a simple experimental investigation that tests the effect of force on an object, why is it important to test one variable at a time?

• It would be impossible to test two variables during an experiment involving force.

• It allows the experimenter to correctly and more easily interpret the results of the experiment.

• It allows the experimenter to formulate a hypothesis both before and after the experiment.

• It is not important to test only one variable at a time.

Students use a fan to move paper boats of different masses across a table. The experimental set-up is shown in the diagram below. Which question is the students most likely trying to answer with this experimental investigation?

• How far does Boat 1 move when the fan is turned on?

• How does the size of a paper boat affect the distance it travels when a constant force is applied?

• Can a fan blow a paper boat across the table?

• How does the mass of a paper boat affect the distance it travels when a constant force is applied?

Based on the picture above, what should be done to improve this experimental investigation?

• The ramps should all be the same height.

• The ramps should be made of different materials.

• The same car should be used on both ramps.

• The experimental design is correct the way it is.

Why do the above boxes move different distances when pushed with the same amount of force?

• Lighter objects have increased friction with the floor.

• Heavier objects have increased friction with the floor.

• Smooth objects have more friction with the floor.

• Rough objects have more friction with the floor.
