Force and Motion

Students use a spring scale to pull different types of shoes across a wood table and record the amount of force required. Which question is this experimental investigation most likely trying to answer?

• How much do the different types of shoes weigh?

• 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?

Students are designing an experimental investigation where they determine how the height of a ramp affects the speed of a toy car by measuring how long it takes for the toy car to travel down different-sized wood ramps. What other scientific tool do the students need in order to complete this experimental investigation?

• Hand lens

• Metric ruler

• Timing device (stop watch)

• Spring scale

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.
