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
What else can I help you with?
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.
Are there two different types of external force?
External forces can generally be classified into two categories: contact forces, which act through direct physical contact between objects (such as friction or tension), and non-contact forces, which act over a distance without physical contact (such as gravity or electromagnetic forces). Both types of forces can influence the motion or interactions of objects.
What are the 2 type of forces?
Push and Pull I'll say 'contact' and 'non-contact'. (I hope nobody is going to come along and say 'balanced' and 'unbalanced', because that's just plain wrong.)
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....
Why dont action-reaction forces cancel out?
they do! for every action is an equal and opposite reaction. To propel a rocket into orbit an equal amount of force is expelled in the opposite direction. This is often dissipated into the atmosphere in the form of heat.
What force act on Earth?
Two main forces act on Earth: gravity, which pulls objects toward the center of the planet, and friction, which opposes motion of objects on the Earth's surface. These forces play a crucial role in shaping and maintaining the Earth's environment and behavior.
What are two forces that act on objects?
Typically there is the force of gravity pulling an object down, and a force that keeps it up - for example, the floor on which an object is standing pushes it up. There may be additional objects involved.
What are the two categories of forces?
The two categories of forces are contact forces, which occur when two objects are physically touching, and non-contact forces, which act between objects that are not in direct physical contact.
What are two ways that forces can act?
Forces can act through contact, where objects physically push or pull against each other, such as a person pushing a box. They can also act at a distance, where the objects do not need to make direct contact, such as gravitational attraction between the Earth and an object.
What objects are similar because they are both areas where forces can act without objects touching?
Two examples of objects that are similar in that forces can act without objects touching are magnets and electric fields. In both cases, forces can act at a distance without direct contact between the objects.
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.
Gravity and what are two forces on earth that act on object?
Gravity is the force that pulls objects toward the center of the Earth, while air resistance is a force that acts in the opposite direction, slowing down objects as they move through the air.
What are two unbalanced forces on Earth?
Two examples of unbalanced forces on Earth are gravity and air resistance. Gravity pulls objects towards the center of the Earth, while air resistance acts against the motion of objects moving through the air.
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.
Why does and object move if the action reaction forces are equal?
An object can still move even if the action and reaction forces are equal because they act on different objects. The equal forces produce opposite accelerations on the two objects, causing them to move in opposite directions. This is described by Newton's third law of motion.
Are there two different types of external force?
External forces can generally be classified into two categories: contact forces, which act through direct physical contact between objects (such as friction or tension), and non-contact forces, which act over a distance without physical contact (such as gravity or electromagnetic forces). Both types of forces can influence the motion or interactions of objects.
