What is the reference to the ability of an object to its original position after it has been tilted slightly?
Stability
Equilibrium
Center of Gravity
Turning Effect
Which of the following is NOT part of States of Equilibrium?
Stable equilibrium
Regular equilibrium
Unstable equilibrium
Neutral equilibrium
When an object is tilted slightly and it topples over, the state is termed?
Unstable equilibrium
Stable equilibrium
Neutral equilibrium
Regular equilibrium
The illustration shows a bunsen burner in 3 different positions. Which of these positions is the most stable?
X
Y
Z
W
The point through which the whole weight of the body acts is called:
Inertial point
Center of gravity
Centroid
Equilibrium
Center of Gravity of an object depends on its:
Weight
Mass
Density
Shape
Center of Gravity is usually located where?
more weight is concentrated
less weight is concentrated
less mass is concentrated
more mass is concentrated
What is the branch of physics that deals with the study of objects at rest?
Statics
Dynamics
Kinematics
Kinetics
In this illustrations, which factors affecting the stability of an object?
Area of the base
Position of CG
Weight of an object
Condition of equilibrium
Define Base of Support
An objects ability to maintain a stable position
The area around the contact points with the ground. The larger it is, the greater stability a person has.
Base of support contributing factors
The point at which all parts of an object are equally balanced
How does a person become more stable in relation to my COG?
The higher the COG the more stable you are
If the COG is in the centre of the BOS you are stable
The lower the COG, the more stable you are
Who is the most stable sports player ?
Who is the least stable sports player ?
A heavy truck on wheels has a platform to attach to it. A man stands on the platform. The truck does not fall over.
Which position A, B, C, or D could be the centre of mass of the whole system (truck, platform and man) ?
A
B
C
D
They would cause the bus become unstable
The would cause the bus to slow down
The would increase the kinetic energy of the bus
The would lower the centre of mass of the bus
A body is in balance and stability when:
Centre of gravity is low
Line of gravity falls within base of support
Centre of gravity is over the base of support
All of centre of gravity, line of gravity and base of support are in one line vertically
Are these people most likely to be stable, unstable, balanced or unbalanced?
Stable
Unstable
Balanced
Unbalanced
Why is stability and balance so important in sumo wrestling?
Because you are simultaneously trying to execute a skill (pushing) while your opponent tries to push you out of stability
Because the wrestlers are big and can easily knock you out of the ring with their low centre of gravity
Because the wrestlers are big, have a naturally high centre of gravity so need to adjust by having a wider base of support and lower centre of gravity
When a human stands in the anatomical position, where does centre of gravity naturally end up?
Belly button
Groin
Chest
Between knees
Is this crazy man likely to be stable, unstable, balanced or unbalanced? Why?
Stable, because he is in the middle of a dynamic movement and his LoG is over his BoS
Unstable, because he is in the middle of a dynamic movement and his LoG is very unlikely to be over his BoS
Balanced, because he is in a static movement and his LoG is likely to be over his BoS
Unbalanced, because he is in a static movement and his LoG is very unlikely to be over his BoS
which one is balance ?
