Julian is skiing down a snowy hill, starting at point A, gliding through point B, and zooming to point C! Which statement about Julian the skier is correct?
Julian has the most kinetic energy at A
The most potential energy is at C
Point B has more potential energy than A
Point C has more kinetic energy than Point B
AJ, Penelope, and Millie are exploring the park and notice different things happening around them. In which of the following situations is kinetic energy turning into potential energy?
When a falling branch hits the ground
AJ running on the track
Penelope's dog chasing a ball
A plane flying in the air
Imagine Emory, Marlee, and Eric are watching a ball race along the twisty path shown below. As the ball zooms from point A to E, which of the following statements best describes its energy?
The ball has the most potential energy at D
The ball has the most kinetic energy at E
The ball has more kinetic energy at C than A
The ball has no energy at E
Darren, Becky, and Marisol are having a contest to see which vase has the fastest moving atoms! Which of the following vases has the most kinetic energy?
a vase in the freezer
a vase coming out of the glass-making oven
a vase sitting in the sun
a vase on a shelf
Jackson and Mariah are having a race with their toy cars! Jackson pulls his car to the top of a ramp, and then lets it zoom down. Which statement best describes what happens to the energy of Jackson's car as it races down the ramp?
chemical to kinetic
potential to kinetic
nuclear to potential
electrical to chemical
Bailee and Jayden are having a friendly science challenge! Bailee drops a rock from the top of a tall building while Jayden watches from below. As the rock falls past points A, B, C, and D, what can you say about its total energy?
There is more energy at point A than point B
The rock has no energy at all
There is more energy at point D than point A
The total amount of energy never changes
Tahlia, Mariah, and Landen are racing toy cars down ramps for a kinetic energy experiment! They each change the height of their ramp and record how fast their car zooms at the bottom. They want to see whose car goes fastest and compare their results. Which statement BEST explains how they should set up their experiment to compare fairly?
each group should use different ramp heights
each group should use the same ramp heights so they can compare directly.
each group should come up with their own experiment
each group should come up with a different independent variable.
Becky, Jazlynn, and Lorenzo are having a blast rolling toy cars down ramps of different heights to see which goes fastest! They’re recording the speed and talking about potential and kinetic energy. Which of the following is true about their investigation?
The investigation is an experiment because they have controlled variables.
The investigation is an experiment as there is only one way to measure energy.
The investigation is not an experiment because it is being done by students.
The investigation is not an experiment because the students are only observing.
Coby, Auriana, and Skylar are having a blast rolling marbles down ramps built with different numbers of bricks! They want to see what happens when they change one thing in their experiment. Which of the following is the independent variable (test variable) in their marble ramp challenge?
the color of the marbles
the height of the ramp
the time
the person
Kierrin and Makenzie are at the bowling alley, and Kierrin rolls a bowling ball straight into the pins! Now, both the ball and the pins are moving. Which statement best compares the energies of the ball AND the pins BEFORE AND AFTER the collision?
The total energy increases after the collision.
Neither of the objects have kinetic energy after the collision.
The total energy is the same, energy from the ball was transferred to the pins.
Both have the same kinetic energy before and after the collision.
Jace, Emory, and Julia are having a friendly competition rolling balls of different masses down ramps of different heights. As they experiment, the height and the mass of the balls both decrease from experiment 1 to experiment 2. How do you think the gravitational potential energy (GPE) and kinetic energy change as the balls roll down the ramps?
both increase
both decrease
GPE increases, kinetic decreases
GPE decreases, kinetic increases
Aveonne and Keylen are racing toy cars down ramps of different heights. Check out the chart and help them figure out: Which statement is supported by the data in the chart?
the mass of the car affects total energy more than the height of the ramp.
the total energy remains the same even if the height of the ramp is changed.
gravitational potential energy stays the same.
Kinetic energy starts at 0 and increases.
Ja'nyla, Coby, and Elizabeth wanted to discover how ramp height affects energy, so they set up an experiment and made a chart. What makes what they did a real experiment, and not just another way to investigate?
they made observations about events
they controlled variables and recorded data
they drew conclusions
they studied one thing under constant conditions
Kayden and Mariah are having an archery contest! Kayden pulls back on the bow string, aims carefully, and lets go. The string snaps back and the arrow zooms through the air. Which statement best describes what happens to the energy in the bow string?
The string has equal amounts of kinetic and potential energy before and after firing the arrow.
Kinetic energy is turned into potential energy as the string is released.
The string starts with no energy and then creates both potential and kinetic energy when it is released.
Potential energy becomes kinetic energy when the string is released.
Keylen, Makenzie, and Mason are riding a roller coaster and are curious about how the car's energy changes along the track! Which of the following statements is true about the path of their roller coaster car?
It has no more energy to use at Point S
There is more energy at Point U than Point Q
The car loses 1/2 of its energy going from Point U to Point V
The total energy of the roller coaster car never changes at any of the points.
