9.3 Guided Reading Name: “What is Energy”
1) Everything around you is full of . Without energy living could not survive.
2) In a slingshot a person energy to the elastic band. When the band snaps back it can transfer energy to a in the slingshot.
3) Work is only done when an object experiences a change in , but can be present even when nothing is happening. It can only be when it is transferred from one object to another.
4) Energy that is stored is known as energy. It is also know as energy of because it results from the relative positions of objects in a system.
5) The energy stored in a rubber band or spring is known as potential energy, while the energy stored between two objects separated by a distance is know as potential energy.
6) Gravitational potential energy depends on the of the objects in a system and the between them. The formula involves force times just like the equation.
7) The energy of a moving object is known as energy. Once an object begins moving it has the ability to do . 8) As an object falls it will and its ability to do work will as it speeds up.
9) Kinetic energy is expressed in because it is calculated using mass and speed squared.
10) In kinetic energy problems speed is so a small increase in speed produces a increase in kinetic energy. This is the reason car crashes are more dangerous at speeds.
11) The sum of both potential and kinetic energy is energy.
12) The energy in particles increases as the object gets and decreases as it down.
13) The atoms in a hotter part of iron are more rapidly than the atoms in the cooler part so they have greater energy.
14) In a chemical reaction the formation of and the breaking of involve changes in energy. This is known as energy and it depends on the positions of the atoms it contains.
15) When a match burns it releases energy from the match and produces and an explosion of hot .
16) Plants use to turn the energy of the sunlight into a chemical energy. 17) Plant energy is stored in and other organic molecules. When you eat food these are transferred to your own cells.
18) The sun’s energy comes from where light atomic nuclei combine to form a nucleus.
19) Nuclear power plants use nuclear to release energy. It involves a heavy nucleus split into two of more nuclei.
20) Electricity is the flow of particles through wires or other materials. Moving electrons can increase the temperature of a wire and make it as in a light bulb.
