When a roller coaster has started racing down the track.
When a roller coaster has stopped on the highest point of the track.
When a sledder coasts at the bottom of a hill.
A rock climber at the bottom of a cliff.

translated
transferred
Transylvania
thermal energy
Which of these is NOT an example of how potential energy is changed into kinetic energy?
A skateboarder jumps into a half-pipe on his/her board
A student wastes time by staring at the walls in science class
A slingshot is pulled back and released, launching a pebble 10 feet into the air

Often, _______________ causes a transfer from kinetic to thermal energy. This is why your hands feel warm after rubbing them together.
friction
spam
sound
fusion
A semi-truck is transporting a heavy load of bricks to a local construction site. He realizes the time and begins to speed up. Unfortunately, he forgot that his route included driving down a steep mountain pass and panics as he steps on the brakes. He looks at his speedometer and realizes he is going 65 mph. After hitting his brakes, he begins to smell burning rubber and hears a squeaking sound.
Identify evidence that supports the claim, energy is neither created nor destroyed, only changed from one form into another.
The driver slams on his brakes.
He looks at the speedometer and realizes he is going 65 mph.
He begins to smell burning rubber and hears a squeaking sound.
A semi-truck is transporting a heavy load of bricks.
When you slide down a regular slide, you feel your skin getting warm and you slow down. When you slide down a water slide, you do not feel your skin getting warm and you keep going fast all the way to the bottom.
Which sentence explains this difference?
The regular slide is taller than the water slide, so more potential energy gets converted to kinetic energy.
Regular slides are metal or plastic, so they are more sticky but the water keeps a water slide from getting sticky.
On the regular slide, friction causes some of the kinetic energy to change to thermal energy, but on a water slide, the kinetic energy does not change.
The water makes your skin feel cold so you don’t feel the thermal energy.
At which point does the roller coaster have the most kinetic energy?
W
X
Y
Z

VISTA, Calif. — The largest skateboard ramp in the world can be found on a 12-acre farm north of San Diego among the green foothills of the San Marcos Mountains. The wooden structure is longer than a football field, as tall as an eight-story building, with a creek bed running through a 70-foot breach.
Approximately 360 feet long, the ramp is 75 feet high at its apex. That is where riders begin their run, speeding down a 180-foot-long roll-in to a ramp that launches them across a 70-foot gap with trapeze netting below. Landing on a 27-foot sloped section, they then boost up to 50 feet above the ground from a 30-foot quarterpipe. A shorter route begins with a 55-foot-tall platform leading to a 50-foot gap, and the 30-foot quarterpipe.
Burnquist, a professional skateboarder, has fallen hard and rolled his ankle, but sustained no breaks. To protect himself, Burnquist wears pads on his hip, tailbone, ribs, elbows and knees. He also wears a helmet and knee braces. All skin, except for his face, is covered by neoprene to prevent severe friction burns. He can wear through a pair of sneakers and gloves each session from sliding on the ramp’s surface during wipeouts.
Which sentence best supports the claim that energy can be changed from one form to another?
"The wooden structure is longer than a football field, as tall as an eight-story building, with a creek bed running through a 70-foot breach."
"To protect himself, Burnquist wears pads on his hip, tailbone, ribs, elbows, and knees."
"Approximately 360 feet long, the ramp is 75 feet high at its apex."
"He can wear through a pair of sneakers and gloves each session from sliding on the ramp's surface during wipeouts."
