What is equilibrium?

• A state of imbalance or instability in a system where opposing forces or influences are equal.

• A state of complete chaos and disorder in a system where opposing forces or influences are equal.

• A state of temporary balance or stability in a system where opposing forces or influences are equal.

• A state of balance or stability in a system where opposing forces or influences are equal.

Define center of mass.

• The center of mass is the point in an object or system where the mass is evenly distributed and the object or system is in balance.

• The center of mass is the point in an object or system where the mass is randomly distributed.

• The center of mass is the point in an object or system where the mass is negligible.

• The center of mass is the point in an object or system where the mass is concentrated.

What is torque?

• Torque is a measure of the force that can cause an object to rotate around an axis.

• Torque is a measure of the force that can cause an object to change shape.

• Torque is a measure of the force that can cause an object to move in a straight line.

• Torque is a measure of the force that can cause an object to accelerate.

How is equilibrium achieved?

• By increasing the concentration of reactants.

• By decreasing the temperature.

• By adding a catalyst.

• By balancing the rates of the forward and reverse reactions.

Explain the concept of center of mass.

• The center of mass is a point in an object or system of objects where the mass is evenly distributed in all directions.

• The center of mass is the point where the object is heaviest.

• The center of mass is always located at the geometric center of the object.

• The center of mass is a fixed point that never changes.

What factors affect the center of mass of an object?

• Distribution of mass and external forces

• Temperature and humidity of the environment

• Color of the object and its shape

• Distance from the object to the nearest star

What is the formula to calculate torque?

• Torque = Velocity x Time

• Torque = Power x Time

• Torque = Mass x Distance

• Torque = Force x Distance

What are the units of torque?

• Watts (W)

• Kilograms (kg)

• Meters per second (m/s)

• Newton meters (N·m) or foot-pounds (ft·lb)

How does the position of the center of mass affect stability?

• The position of the center of mass has no effect on stability.

• The position of the center of mass affects stability by increasing the weight of an object.

• The position of the center of mass affects stability by determining the color of an object.

• The position of the center of mass affects stability by determining the balance point of an object.

Give an example of an object with a low center of mass and an object with a high center of mass.

• unstable pyramid

• short fat pole

• balanced pyramid

• stable pyramid, tall thin pole
