if a refrigerator magnet cant hold a piece of paper against a refrigerator, the forces acting on the magnet must be what?
There can be forces acting on an object while it is at rest, as long as the forces cancel each out. For example: a block laying on a table feels the force of gravity pulling it down, but the table pushes up with the same force. Therefore, the forces cancel and the object remains at rest.
When a book is dropped, the main forces acting on it are gravity pulling it downward and air resistance pushing against it as it falls through the air.
The main forces acting on the falling climber are gravity pulling them downwards and air resistance pushing against their motion. These forces together determine the acceleration of the climber as they fall.
Two forces acting on a book are gravity pulling it downwards towards the Earth and the normal force exerted by the surface it is resting on that pushes back against gravity to keep the book stationary.
If the forward force on an object is equal to the forces of friction and air resistance acting against it, the object will either move at a constant velocity if the forces are balanced, or decelerate if the forces are greater. It is important to consider the overall net force acting on the object to determine its motion.
Forces acting against each other.
Whoa! Force doesn't result from the motion of forces. Let's take it slow. When forces are acting in the same direction, the net force is the sum of the individual forces. Four people, all behind a car, pushing it north. Two men pushing with 200 pounds apiece, two women pushing with 100 pounds apiece. The net force on the car is (200 + 200 + 100 + 100) = 600 pounds north.

There is the apple's weight (mass * gravity) but there is also the air resistance acting against the object's weight.
When a book is dropped, the main forces acting on it are gravity pulling it downward and air resistance pushing against it as it falls through the air.

The forces acting on a falling leaf are gravity pulling it downward and air resistance pushing against it as it falls. These forces determine the leaf's speed and trajectory as it descends towards the ground.
Flying buttresses experience compression forces from the weight of the building they support and tension forces from the forces exerted by the building pushing against them. These forces work together to stabilize and support the walls of the building.
Friction is a force that resists movement by acting in the opposite direction of the motion. Other forces that can work against movement include drag, gravity, and air resistance. These forces can influence the speed and direction of an object in motion.
When you lift an object up, the two forces acting on it are the force of gravity pulling it down and the force exerted by you to lift it up. The force of gravity is acting downwards on the object, while your force is acting upwards against gravity to lift the object.
