Ideal Mechanical Advantage
A crumb falling from a table is an example of
Kinetic Energy
Process of converting one energy to another type of energy
Energy Transformations
Two inclined planes put together form a
Wedge
When you eat and gain energy this is
Chemical energy
How do simple machines make work easier?
by decreasing or redirecting the force needed to complete the task
An object that is not moving has how much kinetic energy
Zero
Fire (Chemical energy) transforms into 2 types of energy
Heat and Light
What is rod attached to the the center of the wheel
an axle
Energy that contains radiant energy you can see and can travel through space
Light energy
A heavy object could be rolled up this simple machine, instead of lifting it straight up. Using this simple machine can save effort, although the object must usually cover more distance if this simple machine is used.
Inclined Plane
Potential energy is greatest when...
the most energy is stored, through mass and height generally
Our bodies convert _________ energy in our food
into _________energy so we can move
chemical, mechanical
What are the six simple machines
Energy that is caused by the movement of charged particles
Electrical energy
The energy the object has because of it's motion or position. It can be kinetic or potential
Mechanical Energy
When does potential energy convert to kinetic energy
One a force is applied (or it begins to move)
An electric lamp has three transformations, what are they?
Electric, Heat and Light
