Forms of Energy
What is stored energy?
What is potential energy.
PE
What is Kinetic energy?
What is, the energy of objects in motion.
Law of conservation of energy
What is " energy that can be neither created nor destroyed, only transferred from one object to another.
On a roller coaster, at the top of the track,
What is, "the highest point of potential energy."
As the roller coaster rolls down the hill, its potential energy is converted to kinetic energy.
It decreases its potential energy.
As it climbs up the hill, it loses kinetic energy, it slows down.
Kinetic energy is affected by what two factors?
What is "Mass & speed"
What is energy in the form of motion?
What is Kinetic Energy.
KE
What is Kinetic Energy in proportion to?
What is, Proportional to the mass of the moving object and grows with the square of its speed.
When the first ball hits the second ball, and stops, is its kinetic energy destroyed?
What is, "No. The energy is transferred to the second ball."
Potential energy is?
What is "stored energy"
Potential gravitational energy is?
What is "the force of gravity can cause objects within a system to interact. The mass of the objects and distance between them are variables that control how much gravitational potential energy is stored in the system.pp
Consider an apple hanging on a tree several meters above earth's surface. The apple and earth make up a system. The apple stores potential energy because of its position above Earth's surface. The apple has the "potential" to fall, so it has gravitational potential energy.
When the apple falls from the tree, its potential energy transforms into kinetic energy, causing it to fall faster and faster until it strikes the ground. A system's energy equals its potential energy plus its kinetic energy, and the total does not change as the apple falls. When the apple is still in the tree, the energy of the system is 100% potential. The moment it has fallen halfway down, the system's energy is 50% potential and 50% kinetic. The moment just as the apple is about to strike the ground, the system's energy is almost 100% kinetic.
Energy can take the forms of?
What is mechanical energy, sound energy, thermal energy, chemical energy, electromagnetic energy, and nuclear energy.
A joule is what?
What is A joule is describes the amount of energy needed to do a certain amount of work or cause a certain amount of changed.
What a driver slams on its brakes, does kinetic energy disappear?
What is, "No, it changes into other forms of energy such as heat, light, and sound,
The type of potential energy in the roller coaster diagram is?
What is 'gravitational potential energy'?
Elastic potential energy?
What is "the energy stored in materials as the result of their stretching or compressing.
Elastic Potential Energy (EPE) can be stored in rubber bands, bungee cords, trampolines, springs, and an arrow pulled back on a bow.
The amount of elastic potential energy stored in such a device is related to the amount of stretch or compression The more stretch or compression there is, the more stored energy there is.
Springs can store elastic potential energy whether they are stretch or compressed. A force is required to compress a spring. The more compression there is, the more force is required to compress it further. for certain springs, the amount of force is directly proportional (equal) to the amount of stretch or compression.
When boiling a pot of water, what variables are there?
What is, these variable include temperature, speed, position, pressure, and motion.
More joules of energy can do what?
What is, "can perform more work" or "cause more change."
As you move faster
What is, "Your kinetic energy increases."
The definition of work is?
"What is
"work is the transfer of energy"
"work is moving an object a distance"
As mass increases, kinetic energy?
What is "Increases"
What is, No. The potential energy only changed forms. Energy cannot be created nor destroyed.
A joule is?
What is "the unit of measurement for energy."
1 Joule is the amount of energy needed to apply a force of 1 newton over 1 meter.
1 joule is equivalent to the energy needed to raise a medium apple (100g) up 1 meter.
Speed and mass?
What is, "do not affect kinetic energy in the same way."
An object's kinetic energy depends on
The object's mass (kinetic energy is directly proportional to the objects mass."
and the object's speed (kinetic energy is directly proportional to the square of the object's speed.
Energy is?
What is "the ability to do work"
As speed/velocity increases, kinetic energy?
What is "increase"
