Warm up * p. 40 John wants to build a racetrack that will allow his toy cars to travel fast when force is applied. Which material should he use? carpet, because friction will be high gravel, because friction will be high plastic, because friction will be low sandpaper, because friction will be low 2. Draw a distance-time graph that shows an object moving at a constant speed.

Energy can be transferred, or converted, from one form to another! Forms of Energy Mechanical Thermal Chemical Electrical Radiant Energy can be transferred, or converted, from one form to another!

Energy associated with the motion of an object. Mechanical Energy Energy associated with the motion of an object. Chewing Sound Frog Dancing

Mechanical Energy= Kinetic Energy + Potential Energy Kinetic energy is the energy of an object in motion. Potential energy is the stored energy of an object due to its position. Mechanical energy is just the total potential or kinetic energy that an object has.

Total energy of the particles in a substance due to heat. Thermal Energy Total energy of the particles in a substance due to heat. All objects give off thermal energy Ice cream melting gains thermal energy

Potential energy stored in chemical bonds. Chemical Energy Potential energy stored in chemical bonds. Food gasoline Stomach Battery

Moving electrical charges that produce electricity and energy. Electrical Energy Moving electrical charges that produce electricity and energy. Lightening Computers/TVs/Radios Lights

Energy that travels in waves Radiant Energy Energy that travels in waves Visible light UV Rays Microwaves

Law of Conservation of Energy Energy cannot be created or destroyed. It is transferred from one form to another.
