Students want to study friction. Which is a testable question?
A) How does the type of surface affect how far a toy car travels?
B) Why do some surfaces feel rougher than others?
C) Which surface is the prettiest?
D) Do students enjoy sliding cars on carpet more than wood?
A) How does the type of surface affect how far a toy car travels?
100
Which surface showed the most friction and explain how you know
The grass because the toy car traveled the least distance.
100
The force that opposes motion is
Friction
200
When a force causes something to move _____ is being done
Work
200
Stored energy is called
Potential Energy
200
Students are testing toy cars on a ramp to see which car goes the farthest. What is a variable they could change to make the cars travel a greater distance?
Ramp incline, Ramp surface,
200
Which graph is wrong - explain why it is wrong:
A
B
B is wrong because it does not show that energy is conserved.
200
Students built small ramps to test how far toy cars would roll. After each trial, they needed to measure both the distance the cars traveled and the time it took. What tools would have been the most useful for the students to use?
Something to measure distance (meter stick, ruler, yard stick, etc).
Something to measure speed (stopwatch, clock, etc).
300
Describe the net force when something is not moving.
The net force = 0 and the forces are balanced.
300

15-20 meters
20-25 meters
20-25 meters
300
The term for all of the forces acting on an object
Net Force
400
Explain how mass affects motion.
The greater the mass, the greater the force is needed to cause motion.
400
The conservation of energy states:
Energy cannot be created or destroyed
400
What is the dependent variable in this investigation?
Distance traveled
400
Explain what the person is doing between minutes 4 and 5.
