500N is applied to an object that moves 6.5 meters. How much work was done? (must include unit)
3250 J
200
The energy of an object due to its motion.
Kinetic Energy
200
A roller coaster after going down a hill mostly has this type of energy.
Kinetic Energy
200
3 objects are at the same height. How would you determine which one has the greatest GPE?
The object with the most mass.
200
A 4.5 kg object is sitting on a 3.0 m shelf. How much potential energy does the object have? (must include unit)
132.3 J
300
This stored energy is due to an objects position and gravity.
Gravitational Potential Energy (GPE)
300
This type of energy can be found in fire and food.
Chemical Energy
300
At what point does the pendulum have the most KE?
B
300
A 1200 kg car is traveling at 25 m/s. How much Kinetic Energy does it have? (must include unit)
375,000 J
400
The sum of an objects PE and KE.
Mechanical Energy
400
The Apple has these two types of energy.
Chemical and Gravitational Potential Energy (GPE)
400
What are the two rules that determine if an object is doing work?
1. Object must move
2. The force and the distance can not be perpendicular to each other
400
A 1250 kg car has 160,000 J of Kinetic Energy. How fast is it going? (must include unit)
16 m/s
500
The rate of energy over time.
Power
500
The slingshot has this type of energy.
Elastic Potential Energy
500
How does friction effect the mechanical energy of a roller coaster?
Friction converts some ME to thermal energy so the ME would decrease.
