Gravity & Free Fall
This is the planet or body in our solar system where gravity is the strongest.
Sun
This is the property of an object that resists any change in its motion.
Inertia
This is the type of potential energy stored in a stretched rubber band or a drawn bow and arrow
Elastic Potential Energy
This is the direction heat always moves.
From hot to cold
These are the two main sources of energy
renewable and non-renewable
This is the only force acting on an object that is in free fall.
Gravity
This is the momentum of a 1,200 kg car traveling at 25 m/s
30,000 kg.m/s
This is the type of energy stored between two magnets forced together at the same poles.
These are the three main ways heat moves.
Conduction, Convection, Radiation
Define Biomass Energy
Energy from burning natural waste materials such as scrap wood, dead trees, unused parts of crops, and animal waste
This scientist first proved that all objects fall at the same rate regardless of mass.
Galileo
This is the velocity of a 3 kg soccer ball with a momentum of 24 kg·m/s
8 m/s
This is what happens to kinetic energy when speed doubles.
Quadruples
These are two materials that are good conductors of heat.
copper, silver, iron, steel
This is the metal nuclear energy comes from and why it is non-renewable.
Uranium
This is what happens to the speed of a falling object every second near Earth's surface.
It increases by 9.8 m/s every second
This is the mass of an object with a momentum of 60 kg·m/s and a velocity of 12 m/s.
5 kg
This is the gravitational potential energy of a 925 kg roller coaster at the top of a 48.5 m hill (include units)
440,101.13 J
These are two materials that are poor conductors of heat.
wood, styrofoam, paper, air
Five types of renewable energy we learned
solar, wind, hydropower, geothermal, and biomass
This is what air resistance does to a falling object
air resistance slows a falling object down by opposing its motion
This is the net force required to accelerate a 1,600 kg car at 4.5 m/s²
7200 N
These are the speeds of Object A (2 kg) and Object B (8 kg) when both have a KE of 50 J
Object A = 7.07 m/s
Object B = 3.54 m/s
This is what hot fluid does and what cool fluid does to cause convection
hot fluid gets lighter and rises, cool fluid gets heavier and sinks, creating a loop
This is why not all countries have the same energy source, with a specific geographic example
Fossil fuels formed in specific places
