Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Problem 16 You can measure acceleration by measuring the deflection of a vertically hanging mass. Suppose an air freshener hangs from the rear view mirror of your car, which is initially at rest. You hit the gas pedal and notice that the air freshener is deflected at an angle of 15 degrees from the vertical. What is your car's acceleration?
Inertia by definition is the propter of things to resist changes in motion. This quantity is directly related to an object’s mass, or how much of ‘something’ and object is made of. Therefore, could Inertia change if your object were to travel into space? Could it change if your object was on the moon? If not, explain how you could change an object’s inertia.
