macroscopically, we are affected daily by
(a) gravitational force -- we are not flying out to s\pace because of it
(b) frictional force -- it is there when you walk or drive or ski
(c) wind -- due to earth's rotation and temperature gradient
(d) buoyancy -- the floating object in water or a rising balloon
(e) tension and compressive forces -- earth crust movement; capillary action; ear drums
(f) magnetic force -- compasses; magnets in motors and generators
(g) electrostatic force -- electric shock; hair clinging to the CRT monitor
etc.
need more work -- the above list is not well categorized.force is a push or a pull that always is a physical contact interaction

In newtons third law the action and reaction forces?
The two forces are of the same magnitude, act in opposite directions, and act on different objects.
What two forces act on you while your in a moving elevator?
1). gravitational attraction between you and the earth 2). upward "normal" force exerted by the floor on the bottom of your feet These are the same forces that act on you while you're standing on anything, whether it's moving or not.
Which is the force that pulls objects toward centre of the earth?
The force that pulls an object toward earth also pulls the earth toward the object.The two forces are equal. Together, we refer to them as the force of gravity.Isaac Newton developed this concept.Gravity. The Earth has more mass than the object, it pulls it towards its' center.
What is the different between contact and non-contact forces?
contact forces are those types of forces which results when the two interacting objects are perceived to be physically contacting each other. while non-contact force is any force applied to an object(or body) by another body that has not indirect contact with each other....
When two forces act on an object in opposite directions the net force is caculated by what?
By the vector sum of the forces. When the forces act exactly in opposite directions, you subtract one force from the other. When they act at some other angle, the calculation is a bit more complicated.
Why does gravity pulls objects to earth?
Gravity is the cause of a pair of forces that attract any two specks of mass toward each other. The forces act along the line between the centers of the objects. As long as you're anywhere near Earth, the forces of gravity pull the Earth toward the center of you, and pull you toward the center of the Earth (and they're equal).
What is it called when two or more equal forces act on an object?
falling objects.
In newtons third law the action and reaction forces?
The two forces are of the same magnitude, act in opposite directions, and act on different objects.
Does gravity pull or push objects towards the earth?
The forces of gravity always pull two objects toward each other.
What is the direction of gravity?
The gravitational forces between two objects act in both directions along the line between their centers of mass. In our daily experience, where one of the objects is always the Earth, we call one of those directions "down" and, as relates to the forces of gravity, we ignore the other direction completely.
What causes an object to fall?
The mutual pair of equal forces between any two masses ... the result of gravity ... causes the Earth and any object on it to fall toward each other. The forces of gravity act along the line between the centers of the two objects, so an object attracted to the Earth will fall toward the center of the Earth. We call that direction "downward".
What two forces you act upon and use when you are standing on earth?
Gravity and atmospheric pressure.
What causes an object to fall downward?
The mutual pair of equal forces between any two masses ... the result of gravity ... causes the Earth and any object on it to fall toward each other. The forces of gravity act along the line between the centers of the two objects, so an object attracted to the Earth will fall toward the center of the Earth. We call that direction "downward".
What will happen if the the same charged object come together?
The electrostatic forces between two objects that have the same kind of charge act in the direction to push the objects apart.
Why a person walk forward during locomotion when according to newton's third law every action has an equal and opposite reaction?
The two forces ("action" and "reaction") act on different objects (you push against the Earth, the Earth pushes against you), so there is no guarantee that forces on one specific object (you, who do the walking) are always balanced.
1 In what direction do the gravitational forces act?
Gravitational forces are attractive only. They act on a line from the center of mass of one object, to the center of mass of another object, and work to bring the two objects closer together.
Why ball dropped in new zealand will not travel in same direction as ball dropped in Scotland?
-- The forces of gravity between two objects act along the line between their centers. -- For objects on Earth, one of the objects involved in mutual gravitational forces is always the Earth, just because it's the biggest mass around. -- So any object dropped on or near the Earth experiences a gravitational force that attracts it toward the center of the Earth. -- The direction from New Zealand toward the center of the Earth is not the same as the direction from Scotland toward the center of the Earth. In fact, they're nearly opposite.
