Forces and Stability Concepts

On a balance beam, if you have a heavy weight on one side, how can you balance it with a lighter weight on the other side?

• Place the lighter weight closer to the center.

• Place the lighter weight further from the center.

• Add more weight to the heavier side.

• Remove some weight from the heavier side.

In a tug-of-war, what happens if one team pulls with more force than the other?

• The rope will break.

• Both teams will stay in place.

• The team pulling with more force will move the other team.

• The rope will stretch indefinitely.

Why is it difficult to stand up from a chair if your head is pressed against a wall?

• Your muscles are not strong enough.

• Your center of gravity cannot move over your feet.

• The wall pushes back with equal force.

• You need to lean backward to stand up.

What causes a standing object to fall over when it is pushed from the top?

• The object becomes too heavy.

• Its center of gravity moves outside its base of support.

• The pushing force is too weak.

• The object's material is too soft.

What happens when a force is applied to an object above its center of gravity?

• It slides along the floor without tipping.

• It becomes lighter.

• It creates a twisting force that can cause it to tip over.

• It immediately breaks into pieces.

Which of the following are the main sensors humans use to maintain balance?

• Skin, hair, and nails

• Eyes, inner ear, and muscle/joint sensors

• Heart, lungs, and stomach

• Teeth, tongue, and nose

How can an object be made more stable and less likely to tip over?

• By making it taller and narrower.

• By raising its center of gravity.

• By lowering its center of gravity.

• By making it lighter.
