Science Mind Map: Mechanical Systems
- 1st Class Lever
- The fulcrum is between the
input and output force, output
force is always opposite of
input force
- Input force is the force applied to a
machine
- Output force is the force that the
machine applies
- Input force is the force applied to a
machine
- Examples are See-Saws or plyers
that remove lids from cans
- The fulcrum is between the
input and output force, output
force is always opposite of
input force
- 2nd Class Lever
- The input and output forces
are in same direction but the
output force is between the
fulcrum and input force
- A fulcrum is the point on the
lever that supports it
- A lever is a rigid bar that is
supported at one point
- A lever is a rigid bar that is
supported at one point
- A fulcrum is the point on the
lever that supports it
- Example is a bottle opener
- The input and output forces
are in same direction but the
output force is between the
fulcrum and input force
- 3rd Class Lever
- Input and output forces
are in same direction but
the input force is
between the fulcrum and
output force
- Examples are swinging a
baseball bat or a rake
- Input and output forces
are in same direction but
the input force is
between the fulcrum and
output force
- Force
- Force is a push or pull
that acts on an object
- Two types of force which
are Contact forces and
Action-at-a-distance force
- Action-at-a-distance forces can
push or pull an object without
touching it, most common is
gravity
- Gravity is the attraction
between two objects due
to their mass
- Gravity is the attraction
between two objects due
to their mass
- Action-at-a-distance forces can
push or pull an object without
touching it, most common is
gravity
- Force is a push or pull
that acts on an object
- Machines
- Machines are any mechanical
system that reduces the amount
of force required to accomplish
work
- Two types of machines:
Complex and Simple
- Complex Machines are machines
that are made up of more than two
or more machines
- Examples are bicycles and scissors
- Examples are bicycles and scissors
- Simple machines are any
of the basic mechanical
devices that apply forces
- Examples are pulleys, which conveys
more distance in a short time or wheel
and axles, which reduce force by moving
heavier objects faster and quickly
- Examples are pulleys, which conveys
more distance in a short time or wheel
and axles, which reduce force by moving
heavier objects faster and quickly
- Complex Machines are machines
that are made up of more than two
or more machines
- Work is the amount of
effort spent when a force
causes an object to
move a distance
- Energy is defines as the ability to
do work
- Types of energy is kinetic
energy and potential energy
- Kinetic energy is when an object moves
- Potential energy is energy
stored in an object
- Kinetic energy is when an object moves
- Types of energy is kinetic
energy and potential energy
- Energy is defines as the ability to
do work
- Two types of machines:
Complex and Simple
- Machines are any mechanical
