100
What does potential energy mean?
Stored Energy based on mass and height/distance
100
What is the definition of kinetic energy?
Moving energy.
The energy of motion!
100
What two main factors affect the amount of gravitational potential energy an object has?
Mass and height/distance!
100
Is a falling raindrop an example of Potential or Kinetic energy and WHY?
Kinetic energy, because it is moving!
100
What unit of measure is used for energy?
Joules
200
True or False?
A stretched rubber band has elastic potential energy.
True
200
True or False?
A parked car in a driveway has kinetic energy?
False.
It is NOT moving.
200
What two main factors affect the amount of kinetic energy an object has?
Mass and speed/velocity!
200
Water stored behind a massive dam is an example of what type of energy?
Potential energy.
200
What do you get when you add an object's potential energy and its kinetic energy together.
PE + KE = ?
Mechanical Energy!
PE + KE = Mechanical Energy
300
Why does a book sitting on high shelf have more potential energy?
It has a higher distance/height, so it has more potential energy.
300
Which has MORE kinetic energy?
A running turtle or a running cheetah?
Cheetah - due to its much higher speed/velocity.
300
If you double the speed of a moving car, which type of energy increases drastically?
Kinetic energy
300
What type of energy does a charging bull running across a field have?
Kinetic energy.
Because he is moving!
300
On a rollercoaster, where is potential energy at its absolute highest?
At the top of the highest hill.
400
When does a bow have its maximum potential energy?
When it is pulled back/stretched completely!
400
When does a snowboarder have the highest amount of kinetic energy on a halfpipe hill?
At the very bottom of the hill!
That is where PE is the lowest and KE is the greatest!
400
An elephant and a mouse are standing on the exact same branch of a tree.
Which has MORE potential energy and WHY?
The elephant has more PE because it has more Mass!
400
What type of energy does a climber resting halfway up a cliff have?
Potential Energy.
Because he isn't moving!
400
On a roller coaster where is the kinetic energy at its absolute highest?
At the bottom of the hill.
That is where KE is the greatest and PE is the lowest.
500
Alex is standing completely still on top of a large boulder.
Does he have potential energy?
Yes, he has potential energy due to his height/distance from the ground!
500
May is standing still in the school lunch line.
Does she possess kinetic energy?
No.
She is not moving. She has no speed/velocity!
500
A 10 kg bowling ball and a 1 kg are rolled down a lane at the exact same speed, 5 miles per hour.
Which ball has more kinetic energy and WHY?
The 10 kg ball has more kinetic energy because it has more MASS!
500
What type of energy is striking a match against a box to create a flame?
Kinetic energy
Striking a match is moving energy!
500
State the Law of Conservation of Energy.
Energy cannot be created or destroyed, only transferred or transformed from one form to another.
