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?
A. How much do the different types of shoes weigh?
B. How does the type of shoe affect the amount of force required to pull it?
C. How does a spring scale work?
D. How much force is required to pull the high heel shoe?
Which of the procedures below would provide the most reliable data?
A. Pull each type of shoe once and record the results.
B. Pull each type of shoe twice and record the results of each trial.
C. Pull each shoe five times and record the results of each trial.
D. All of the procedures have the same reliability.
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?
A. Hand lens
B. Metric ruler
C. Timing device (stop watch)
D. Spring scale
Based on the picture above, what should be done to improve this experimental investigation?
A. The ramps should all be the same height.
B. The ramps should be made of different materials.
C. The same car should be used on both ramps.
D. The experimental design is correct the way it is.
Why is it important to conduct multiple trials in a simple experimental investigation?
A. Repeated investigations make the results more reliable.
B. Repeated investigations make the results less reliable.
C. Repeated investigations make the results more realistic.
D. Repeated investigations make the results correct.
The diagram above shows four identical boxes filled with different materials that need to be pushed across the room. Equal force is applied to each box for 15 seconds. Which box will move the farthest after 15 seconds?
A. Box 1
B. Box 2
C. Box 3
D. Box 4
Why do the above boxes move different distances when pushed with the same amount of force?
A. Lighter objects have increased friction with the floor.
B. Heavier objects have increased friction with the floor.
C. Smooth objects have more friction with the floor.
D. Rough objects have more friction with the floor.
What experimental tool would be most useful in this experimental investigation?
A. Hand lens
B. Spring scale
C. Calculator
D. Meter stick
Friction is the force between two objects when they come into contact with each other. More friction occurs when an object rubs or move against a _________________________ surface.
A. Smooth
B. Rough
C. Shiny
D. Flat
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?
A. How far does Boat 1 move when the fan is turned on?
B. How does the size of a paper boat affect the distance it travels when a constant force is applied?
C. Can a fan blow a paper boat across the table?
D. How does the mass of a paper boat affect the distance it travels when a constant force is applied?
What other scientific tool do the students need in order to complete this experimental investigation?
A. Timing device (stop watch)
B. Meter stick
C. Spring scale
D. Calculator
What is the unit of measure of force?
A. Newton
B. Gram
C. Meter
D. Kilogram
