Exploring Balanced and Unbalanced Forces

Why do tug-of-war games with balanced teams last longer?

• Because the teams are uneven in strength

• The game rules require more time

• Due to the balanced forces exerted by both teams

• Because the rope is usually longer

What is the state called when a bird rests on a branch without moving?

• Velocity

• Motion

• Equilibrium

• Acceleration

What happens when an additional bird lands on the branch?

• Both birds fly away

• The branch breaks due to unbalanced forces

• The branch remains stable

• The branch extends

What keeps the bike moving at a constant speed under balanced forces?

• The bike's color

• Pedaling force equalizing the resistive forces

• Lack of gravity

• A flat road

What immediate effect does breaking the chain have on the bike?

• It continues at a constant speed

• It stops instantly

• It decelerates and eventually stops

• It accelerates

When are forces considered balanced?

• When they cause acceleration

• When they are of different sizes

• When they are the same size and act in opposite directions

• When they only act in one direction

What is a direct result of unbalanced forces?

• No change in motion

• Constant speed

• Equilibrium state

• Change in motion

What should be considered when forming a tug-of-war team to ensure a balanced game?

• Using a longer rope

• Balancing the force capabilities of both teams

• Choosing the strongest participants

• Playing on different surfaces
