FearOfPhysics.com: The Basic Interactions

Inertia (again)

An object with a small mass is moving toward the right. Suddenly a force is applied to it, pointing up and to the left. Watch how the object's motion changes in response to this force. Suppose everything was kept the same, but the mass of the object was increased tenfold. How would the object respond the the force now?

exactly the same
would respond slower
would respond quicker
