ROTATIONAL MOTION

In a balance scale, what is kept equal on both sides?

• Forces only
• Distances only
• Masses only
• Moments

What is the product of force and distance in rotational motion called?

• Energy
• Power
• Impulse
• Moment

Why is the mass of the lever considered negligible in ideal cases?

• To make it float
• To reduce cost
• To increase speed
• To simplify calculations by ignoring its weight

What is the role of the effort in a lever?

• To support the fulcrum
• To measure distance
• To create friction
• To apply force to lift the load

In the equation R - F₁ - F₂ = 0, what does this represent?

• Rotational equilibrium
• Energy conservation
• Momentum conservation
• Translational equilibrium
