speed and time
speed and mass
speed, mass, and time
Bonito has potential energy while he is in the starting blocks, getting ready to run his 5-kilometer race. Which of the following statements are true about his potential energy? Choose the three statements that apply.
It can do work.
It is stored energy.
It might be used later.
It can be changed into kinetic energy.
George rolled four different types of paper into four different cylinders. Identical 10 centimeter rubber bands were placed around the cylinders to hold the paper in place. Each number in the answer choices is the diameter of one of the cylinders. Which cylinder has the rubber band with the greatest elastic potential energy?
5 centimeter
10 centimeter
20 centimeter
25 centimeter
Two sites on the same river have been surveyed as a place to build a dam. The dam will be part of a hydroelectric power plant. Site A is at the top of a 50-meter waterfall. Site B is at the top of a 35-meter waterfall. Which answer correctly describes where the water will have the greater gravitational potential energy to be converted into electricity?
Site A
Neither site has gravitational potential energy to convert to electricity.
Both sites will produce the same amount of electricity as the water flows over the water fall.
At both sites the water has the same gravitational potential energy.
Which of the following is an example of kinetic energy?
a roller coaster paused at its highest point
a bicycle rolling downhill
a boulder sitting at the top of a mountain
a ball at the top of its trajectory
Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have? Choose the two statements that apply.
elastic
gravitational
kinetic
stretched
Choose the phrase and the number that correctly complete the paragraph.
Jaime has a 20-N bird feeder on a 2-m pole in his yard. The gravitational potential energy (GPE) of the bird feeder is the result of ______________________.
its speed and mass
its gravitational pull of the Earth
its kinetic energy
its elasticity
Chloe is training for her first half-marathon, which requires her to run 21.1 km. Before she runs, she carefully chooses the foods that will give her the energy her body requires for the race. She stands still at the starting line, and then she starts running, her body warming up as she runs.
Which three energy transformations take place in this example?
chemical energy to kinetic energy
chemical energy to thermal energy
mechanical energy to chemical energy
potential energy to kinetic energy
As of 2017, the tallest roller coaster in the world is the Kingda Ka, located at Six Flags Great Adventure in Jackson, New Jersey. It stands 139 m tall and, at one point, the cars drop 127 m! Roller coasters are a great way to investigate energy. Look at the diagram of a roller coaster, and answer the following questions.
At what point on the track does the car have the greatest potential energy? The greatest kinetic energy?
At the ending point; at the starting point
At the starting point; at the ending point
At the highest point on the track; at the lowest point on the track
At the lowest point on the track; at the highest point on the track
Her teacher told Fatima that all types of energy are kinetic energy, potential energy, or both. Fatima drew the diagram below to help her organize this information. She then sorted each type of energy into its correct category.
Types of energy: chemical, electrical, electromagnetic, mechanical, nuclear, thermal
chemical
electromagnetic
mechanical
thermal
Johanna took her younger brother to the playground because he likes to swing. Look at the diagram below that shows Johanna pushing her brother on a swing.
After Johanna pushes for a while, she begins to feel tired. What type of energy is transformed into the kinetic energy she uses?
chemical
electrical
nuclear
thermal
