Explain how you would use potential and kinetic energy to speed up a roller coaster?
Increasing the potential energy by increasing the height of the starting point.
Jacob investigated the effect of ramp height on the speed of a toy car. What is the test variable (independent variable)?
The ramp height
Where does a roller coaster have the greatest potential energy?
A the highest point of the track.
Where does a roller coaster have the greatest amount of kinetic energy?
At the lowest point of the track
When does a pendulum have the greatest kinetic energy and the least potential energy?
When the ball is in the middle or bottom position. (Lowest point)
Ricardo is investigating the effect of salt on the boiling point of water. What was the outcome variable (dependent variable)?
The boiling point of water.
When does a rubber band have the greatest elastic potential energy?
When it is stretched
When does a snowboarder have the highest kinetic energy?
At the bottom of the hill?
Is hydroelectric, potential or kinetic energy and why?
Kinetic energy, because the water is moving.
A student examines the effect of the number of D batteries in a closed circuit on the brightness of a light bulb. Which variable should the student keep constant?
The type of Batteries
How does the height of an object affect its gravitational potential energy?
The higher an object is the more potential energy it has.
Explain how you would change a marbles potential energy into kinetic energy?
Answers will vary.
Explain the inverse relationship between kinetic energy and potential energy.
When kinetic energy is low, potential energy is high, and when potential energy is high, kinetic energy is low.
Miley is investigating the relationship between an object's mass and its force of impact. What is the outcome variable (dependent variable)?
The force of impact.
