1). Yes. An object can be moving if the net force acting on the object is zero.
A non-zero net force is required to CHANGE the object's motion ... speed it up,
slow it down, or change its direction. But no force is required to keep it moving
at a constant speed in a straight line.
2).a). The motion of the box changes, from not moving to moving.
So the forces acting on it must be unbalanced.
2).b). The motion of the box doesn't change. It goes from not moving
to still not moving. So the forces acting on it must be balanced.
2).c). The motion of the box changes. Its speed decreases.
So the forces acting on it must be unbalanced.
Answer:
electrostatic force
Explanation:
Electrostatic force is the force that exists between electric charges on stationary charged bodies
Reaction force is the ball pulling up on the Earth. Every action has an equal and opposite reaction, so when the Earth pulls on the baseball, the baseball pulls back on the Earth with equal force
They are called radicals.................
