Which of the following scenarios best demonstrates an unstable equilibrium?

• A book balanced on its edge

• A ball at the bottom of a hill

• A pencil standing on its point

• A marble in the center of a bowl

What is the role of friction in maintaining the stability of an object?

• It reduces the forces acting on the object

• It increases the chances of tipping over

• It opposes sliding and helps maintain position

• It prevents gravitational pull

How does the center of gravity affect the stability of an object?

• The lower the center of gravity, the more stable the object

• The higher the center of gravity, the more stable the object

• A higher center of gravity makes it easier for the object to move

• The center of gravity does not affect stability

Which of the following objects would be the most stable?

• A pencil balanced on its tip

• A book balanced on its edge

• A football resting on its side

• A ball sitting on the ground

What effect does increasing the base of support have on the stability of an object?

• It increases the object’s center of gravity

• It decreases the object’s base of support

• It makes the object more stable

• It makes the object easier to tip over

When does an object reach its tipping point?

• When the center of mass is below its base of support

• When the center of mass is above its base of support

• When the object is moved slowly

• When it is in stable equilibrium

What type of system is described when small disturbances cause large changes in its position or state?

• Stable

• Unstable

• Neutral

• Balanced

How does the shape of an object affect its stability?

• It determines the gravitational pull on the object

• It impacts the center of gravity

• It affects the friction between surfaces

• It does not influence stability
