Kinetic Energy
An object needs to be _____ in order to have kinetic energy.
What is moving?
Other answers: In motion
Potential energy is shown when an object is _____.
What is at rest?
Other answer choices: Still, not moving, resting.
The amount of matter in an object.
What is mass?
A glass of water sitting on the edge of a table will likely have more _____ energy since it is resting.
What is potential energy?
This is the total amount of energy in a moving object if that object contains 100J of potential and 150J of kinetic energy.
What is 250J of total energy?
An object would have the most kinetic energy at the _____ of a large drop or hill.
What is the bottom?
As ____ increases, potential energy also increases.
What is distance?
Stored energy.
What is potential energy?
This type of energy can be shown by rubbing a felt cloth on a balloon.
What is static or electrostatic energy?
A book is resting on the shelf with 550J of potential energy. We can figure out that by the time the book reaches the floor it will have this much kinetic energy.
Kinetic energy is measured in _____.
Hint: What is the unit of measurement NOT just the abbreviation. (Spelling doesn't matter)
What are joules (J)?
This type of potential energy is shown an when energy is stretched or compressed in an object.
What is elastic potential energy?
Energy of motion.
When water from a dam is released, its energy turns from ____(1) energy to _____(2) energy, turning the blades of a water turbine generator.

What is potential (1) and kinetic (2)?
Picture a pendulum. If the total energy is 100J, and the pendulum is halfway from the highest and lowest point, we can assume the pendulum has this many joules of kinetic energy.
What is 50J of kinetic energy?
As ____ and ____ increase, kinetic energy also increases.

What are mass and speed?
This type of potential energy is shown when forces are pulling an object down to Earth's surface.
What is gravitational potential energy?
This is the ability of a system to do work or complete a task.
What is energy?
This type of energy can be shown by pulling back on a rubber band before shooting it.
Hint: Answer with the specific type of energy not just kinetic/potential.
What is elastic potential energy?
A moving object has a total energy of 12,540J. If 8,040J are potential energy, we can assume there is this much kinetic energy.
What is 4,500J of kinetic energy?
When on object comes to a stop, energy can be transformed into other sources such as light, sound, and ____.
Hint: Think of how you feel after a long run.
What is heat?
This type of potential energy can be shown by charged particles moving closer or farther away from each other.
What is static or electrostatic potential energy?
States that energy cannot be created or destroyed.
What is the law of conservation of energy?
Object A has 20g of mass and is 10m from the ground. Object B has 15g of mass and is 15m from the ground. Object C has 20g of mass and is 15m from the ground. Object D has 15g of mass and is 10m from the ground.
This object has the most potential and kinetic energy.
What is object C?
Calculate the momentum of a 12g object moving at 4m/s.
Momentum is calculated by MassXSpeed.
What is 48?
