opposite direction. Each member of the action/ reaction pair of forces acts on a different object; one force acts on the ban and the other on the bat. If no other forces are present, the objects are accelerated in opposite directions as long as the forces are applied. Review Questions tir 55. As the mass of an object on Earth's surface decreases, what happens to the inertia and weight of the object? 59. A cart is uniformly accelerating from rest. The net force acting on the cart is (1) decreasing (2) zero (3) constant but not zero (4) increasing (1) Inertia decreases, and weight decreases. (2) Inertia decreases, and weight remains the same. (3) Inertia increases, and weight decreases. (4) Inertia remains the same, and weight remains the same. 60. An 8.0-kilogram block and a 2.0-kilogram block rest on a horizontal frictionless surface. When horizontal force F is applied to the 8.0-kilogram block, it accelerates at 5.0 meters per second? east. If the same force was applied to the 2.0-kilogram block, the magnitude of the block's acceleration would be 56.
