What 3 elements make up a lever system?
Effort, Cranium, Load
Load, Humerous, Fulcrum
Fulcrum, Effort, Desire
Load, Effort, Fulcrum
What is the Falcrum?
The fixed point that the lever turns on, or is supported by. It is where movement stems from.
The force needed to create the movement
The weight or resistance
What is the Effort?
The weight or resistance
The force needed to create the movement
The fixed point that the lever turns on, or is supported by. It is where movement stems from.
What is the Load
The force needed to create the movement
The fixed point that the lever turns on, or is supported by. It is where movement stems from.
The weight or resistance

a first class leaver is when....
The FULCRUM is between the EFFORT and the LOAD
LOAD is between the FULCRUM and EFFORT
the EFFORT is between the FULCRUM and the LOAD
a second class lever is when...
EFFORT is between the LOAD and the FULCRUM
the FULCRUM is between the EFFORT and the LOAD
LOAD is Between the FULCRUM and the EFFORT
A third class lever is when...
the LOAD is between the FULCRUM and the EFFORT
the EFFORT is between the FULCRUM and the LOAD
the FULCRUM is between the EFFORT and the LOAD
Which lever is this an example of?
1st Class Lever
2nd Class Lever
3rd Class Lever
Which lever is this an example of?
1st Class Lever
2nd Class lever
3rd Class Lever
Which lever is this an example of?
1st Class Lever
2nd Class Lever
3rd Class Lever
What is Mechanical Advantage?
When the resistance is stronger than the effort
When the fulcrum is closer to the effort
When the effort is greater than the resistance
when the effort arm is shorter than the resistance arm
How can we make the body's lever more effective?
making the lever longer by using equipment such as racquets, bats or oars
shortening the lever by removing equipment meaning the fulcrum and load are closer
Which is an example of a 1st class lever?
Which is an example of a 2nd class lever?
Which is an example of a 3rd class lever?
Pick one of the correct planes of movement.
Sagittal Plane
Frontal Plane
Flying Plane
Transverse Plane
Directional Plane
Which plane spilts the body into right and left sides?
(a)
the (a) Plane Splits the body into a front and a back
What type of plane splits the body into an upper and lower half?
(a)
Imaginary straight lines through the body which all movements rotate around are also known as what?
Points of Movements
Points of Rotation
An Axis (Axes)
Planes
the vertical axis runs vertically from top to bottom. what type of movement occurs around this axis?
Rotational
Lateral
Vertical
A forward somersault during diving would move around which Axis?
the Vertical Axis (top to bottom)
the Frontal Axis (Left to right)
the Sagittal Axis (front to back)
A cartwheel would occur on an axis that runs through the body from front to back. What is it called?
Vertical Axis
Frontal Axis
Longitudinal Axis
Sagittal Axis
How do Axes and Planes combine to work together?
