WORK AND ENERGY

Is it work?

FORCE MAKES SOMETHİNG MOVE WORK

Which statements are the examples of work ? A teacher applies a force to a wall and becomes exhausted. A book falls off a table and free falls to the ground. A waiter carries a tray full of meals above his head by one arm straight across the room at constant speed. A rocket accelerates through space.

ANSWERS NOT WORK WORK

FORMS OF ENERGY Kinetic energy: This is an energy due to motion Scaler quantity

FORMS OF ENERGY POTENTIAL ENERGY position shape state

FORMS OF ENERGY GRAVITATIONAL POTENTIAL ENERGY Gravitational potential energy is the energy stored in an object as the result of its height.

Use this principle to determine the blanks in the following diagram Use this principle to determine the blanks in the following diagram. Knowing that the potential energy at the top of the tall platform is 50 J, what is the potential energy at the other positions shown on the stair steps and the incline? http://www.physicsclassroom.com/class/energy/u5l1b.cfm

Elastic Potential Energy A stretched rubber band can do work when released, so can a compressed spring. Both have elastic potential energy.

Chemical Potential Energy When a fuel burns, its energy is released by chemical reactions. The energy stored in the fuel is called chemical potential energy.

Electrical Potential Energy In circuits, the current is a flow of tiny charged particles called electrons. These come from atoms. Electrons can transfer energy from a battery or a light bulb. They have electrical potential energy.

Nuclear Potential Energy An atom has a nucleus. This is made up of particles. In some atoms, the particles become rearranged, or the nucleus splits, and energy is released. This is called nuclear potential energy.

Thermal Energy When hot objects cool down, their atoms and molecules slow down and lose energy. This is known as thermal energy. Engines use thermal energy to do work.

Radiated Energy The Sun radiates light. Loudspeakers radiate sound. Light and sound both travel in the form of waves. These carry energy.
