TYPES of Energy
What are the two types (categories) of energy?
Potential and Kinetic
How many forms of energy are there? What are they?
6:
Chemical
Electrical
Mechanical
Electromagnetic
Nuclear
Thermal
A car battery
Chemical
Height and Mass affects
Potential Energy
This is the ability to do work or cause change.
Energy
Which type of energy has to do with the motion of an object?
Kinetic
Which form of energy do you see occur with your own eyes every day? You see it when people or things move and cause changes around them.
Mechanical Energy
Running Cross Country
Mechanical
Mass and Speed affects
Energy stored by something that can stretch or compress
Elastic Potential Energy
Which type of energy is affected by the size, mass and height of an object?
Potential Energy
Explain how chemical energy can create electrical energy.
Batteries have stored chemical energy that give power to electronic devices.
The Sun itself
Nuclear
Work and Time
Power
Energy being transferred to another object
Work
Explain the relationship between Kinetic and Potential energy when you go down a slide.
Name 3 different types of energy that are needed/ occur when you use a microwave oven
Electricity powers Microwaves
E.M. waves cook the food
Thermal energy is produced
Mechanical makes the plate move, door open, buttons work
UV Rays from the Sun
Electromagnetic
Particles and movement
Thermal Energy
Potential energy that depends on the height of an object
Gravitational Potential Energy
Explain What happens to both the Potential and the Kinetic energy when an airplane takes off.
As the airplane starts on the runway and takes off it speeds up increasing the kinetic energy.
The mass of the airplane doesn't change but as the elevation increases, the potential energy of the plane (and everyone in it) increases also.
Which form of energy provides the MOST power and energy transfer?
Nuclear Energy
How can a car have 5 out of the 6 forms of energy?
...
Electrons and Movement
Electrical Energy
The rate at which work is done (work and time)
Power
