Force
What is the unit for force
Newtons
What is the unit for work
Joules
What are the units for Mechanical Advantage
There are none
What is the point where a lever balances on
A Fulcrum
Kinetic energy is
In anything that moves
What is force
a push or pull
What is work
The transfer of energy that occurs when a force makes an object move
What is Mechanical Advantage
the amount of times by which a machine can increase or decrease an effort force
A lever is an example of what
a simple machine
Potential energy is
anything that has the ability to move
Force x Distance =?
work
Work happens when
when the motion and force are moving in the same direction
Which type of Mechanical Advantage is found using forces for
Actual MA
There are how many types of levers
3
What is Mechanical Energy
the total kinetic and potential energy in a system
What is an input force
the amount of force you put in
If the force is 10N and the distance is 7m what is the work
70J
What is the method of finding Ideal MA for levers
Effort Arm length divided by Load Arm length
What lever has the load force in the middle
a Class 2 lever
What is Chemical Potential Energy
Energy stored in chemical bonds
Ideal MA is impossible because of what 3 forces
slippage, distortion, and friction
When does negative work occur
When the force and motion are in opposite directions
How do you find the ideal MA for pulleys
Count the taut ropes
If the load arm is 10m longer than the effort arm of 2m what is the MA
-6 MA
