Question

The force that causes an object to move in a circle is called the The centrifugal force The centripetal force There must be both centripetal and centrifugal force Nonsense! No force is required to cause an object to move in a circle Inertia A tin can on the end of a string moves in a circle because There is an unbalanced inward force acting on the can The can continuously pulls the string o Once the can starts moving its inertia makes it continue There is an unbalanced force on the can pulling it outward The outward force on the can balances the inward forces A car travels in a circle with constant speed. The net force on the car Is zero because the car is not accelerating o ls directed away from the center of the curve Is directed toward the center of the curve Is directed forward in the direction of travel None of the above What is the direction of the force that acts on cloths in the spin cycle of a washing machine? O Outward Inward o Tangent to the drum O None of these

Answer 1

A.The force that courses an object to move in a circle is called the "The centripetal force".

B.A tin can on the end of a string moves in a circle because "There is an unbalanced inward force acting on the can".

C.A car travels in a circle with constant speed.The net force on the car "Is directed toward the centre of the curve".

D.The direction of the force that acts on clothes in the spin cycle of a washing machine is "Inward".
