Question

Why would it require greater force to start a refrigerator moving than to start a dog moving?

Answer 1

Because refrigerator has a greater inertia than dogs.inertia is the force posses by a body that tends to resist force applied..so u need to apply a greater force on a fridge than dogs.

Answer 2

Another explanation would be frictional.

A fridge has more mass than a dog, therefore the Coulomb friction is greater.

\[F_f = \mu mg \]

Answer 3

because dog can walk alone:)
