Understanding Centripetal and Centrifugal Forces

What force causes the nut to move towards the center when the balloon is rotated?

• Magnetic force

• Centripetal force

• Frictional force

• Gravitational force

In the cup and water activity, why does the water not spill when the cup is upside down?

• The water evaporates quickly

• Centrifugal force keeps the water in place

• The cup is sealed

• The water is glued to the cup

What is the purpose of the spinner activity?

• To explain frictional force

• To show gravitational pull

• To illustrate centrifugal force

• To demonstrate magnetic force

How can the balls be separated in the plastic glasses activity without touching them?

• By using a magnet

• By using centrifugal force

• By applying heat

• By shaking the assembly

What is the main difference between centripetal and centrifugal forces?

• Centripetal force only acts on liquids

• Centrifugal force is a type of gravitational force

• Centripetal force is stronger than centrifugal

• Centripetal force pulls towards the center, centrifugal pushes away

Which of the following is an example of centrifugal force in daily life?

• A car turning a corner

• A pendulum swinging

• Clothes spinning in a washing machine

• A satellite orbiting Earth

How can butter be separated from buttermilk using the concepts learned?

• By adding salt

• By freezing the mixture

• By using centrifugal force

• By heating the mixture

Why is the Earth bulged at the equator?

• Due to gravitational pull

• Because of centrifugal force

• Because of tectonic activity

• Due to magnetic fields

What role does centripetal force play in the revolution of planets?

• It pushes planets away from the sun

• It has no effect on planetary motion

• It keeps planets in orbit around the sun

• It causes planets to rotate on their axis

How do pathologists use centrifugal force in their work?

• To heat samples

• To magnify samples

• To separate blood cells from plasma

• To freeze samples
