6. What is Centripetal force?

What is centripetal force?

• A force that causes a change in mass
• A force that causes linear motion
• A force that causes an object to change color
• A force that causes circular motion

What is the difference between centripetal force and centrifugal force?

• Centripetal force is perpendicular to velocity, and centrifugal force is parallel to velocity

• Centripetal force is a real force, and centrifugal force is a fictitious force

• Centripetal force causes linear motion, and centrifugal force causes circular motion

• Centripetal force is an external force, and centrifugal force is an internal force

What is required for circular motion?

• Centrifugal force
• External force
• Gravitational force
• Centripetal force

What affects the amount of centripetal force needed for circular motion?

• The mass of the object

• The color of the object

• The radius of the circle

• The linear velocity of the object

What are some sources that can provide centripetal force?

• Tension
• Friction
• External forces like gravitation
• Centrifugal force

What is centrifugal force?

• A real force that pushes objects away from the center of rotation
• A fictitious force that appears in a non-inertial frame of reference
• A force that causes linear motion
• A force that causes an object to change shape

What is the purpose of a pseudo force?

• To convert non-inertial to inertial frame of reference
• To make objects move faster
• To create circular motion
• To increase the mass of the object

What is required to maintain circular motion?

• A decrease in centripetal force

• An increase in centrifugal force

• An increase in centripetal force

• Keep the centripetal force the same

Which force is required for a rotating object?

• Magnetic force
• Centrifugal force
• Gravitational force
• Centripetal force

Should centrifugal force be used in scientific or engineering analyses?

• Yes, it is a real force and important
• No, it is a pseudo force and should be avoided
• Only in some cases
• It depends on the object
