Example Problems
100
This is the ability to do work
What is energy?
100
This is what GPE stands for
What is gravitational potential energy?
100
This is the unit that we use to measure work and energy.
What is a Joule?
100
This is evidence of work being done.
What is movement?
200
This is the energy of movement
What is kinetic energy?
200
These two factors determine the energy that is stored in an object due to gravity.
What are mass and the object's height above the ground?
200
This is the unit that we use to measure mass.
What is a kilogram?
200
According to the picture, this person has more GPE. (Justify your answer to double your points!!)
What is Person B? (Because he is higher off of the ground)
300
This is energy that is stored
What is potential energy?
300
This is the formula that we use to calculate an object's GPE.
What is GPE = (mass) x (10) x (height above the ground)
300
This is the unit that we use to measure distance.
What is a meter?
300
At which point does the object have the most kinetic energy? (Justify your response to double your points!)
What is point B? (Because all of the GPE has been converted to KE)
400
This is energy that is stored due to an object's position above the ground
What is gravitational potential energy
400
This is how much energy is stored in a 2 kg object that is 10 meters above the ground.
What is 200 J?
400
These are the units that we would use to describe the GPE that is stored in an object
What are Joules?
400
According to the picture, this object has the most kinetic energy.
What is the car? (Because it is moving faster)
500
These are the variables that one needs in order to calculate an object's gravitational potential energy
What are mass, height off of the ground, and acceleration due to gravity (or the number 10)?
500
This is the mass of an object that is storing 450 J of energy and is 9 meters above the ground.
What is 5 kg?
500
These are the units that we would use to describe how high an object is above the ground.
What are meters?
500
According to the picture, this object has the most GPE. (Justify your response to double your points!)
What is the elephant? (Because the elephant has a greater mass)
