What else can I help you with?
Is support force a contact force?
Yes, support force is a contact force. It occurs when an object rests on a surface and the surface exerts an upward force to counteract the object's weight, preventing it from falling.
Is muscular force a contact force why?
Yes, muscular force is a contact force. This is because muscle fibers within the body physically contract and apply force directly via contact with an object or surface, such as when lifting a weight or pushing a door.
Why is weight considered a non contact force?
Weight is considered a non-contact force because it acts at a distance without direct physical contact between objects. It is the force of gravity pulling an object toward the center of the Earth, regardless of any physical contact between the object and other bodies.
Why does weight affect frictional force?
Weight affects frictional force because friction is a force that opposes motion and is directly proportional to the normal force acting on the object. The normal force acting on an object is influenced by its weight, so an increase in weight results in a greater normal force and therefore a greater frictional force.
What type of contact force is perpendicular to the surface of contact?
Normal force is a type of contact force that is perpendicular to the surface of contact. It is the force that a surface exerts on an object placed on it, acting in a direction perpendicular to the surface.
Is support force a contact force?
Yes, support force is a contact force. It occurs when an object rests on a surface and the surface exerts an upward force to counteract the object's weight, preventing it from falling.

Normal force is a type of contact force that is perpendicular to the surface of contact. It is the force that a surface exerts on an object placed on it, acting in a direction perpendicular to the surface.
When your weight is greater than mg and when your weight is zero?
When your weight is greater than mg, the normal force acting on you will be greater than your weight, resulting in an upward force. When your weight is zero (for example, during free fall), the normal force is also zero as there is no contact surface to exert a force on you.
Why force required to move box of same weight changes in case of different surfaces in contact?
Force required to move a box of the same weight changes in the case of different surfaces in contact due to friction.
Is pressure a contact or non-contact force?
Pressure is a contact force because it arises due to the interaction between two objects that are in contact with each other. It is the force applied perpendicular to the surface of an object due to the external load or the weight of the object itself.
Is a force a contact or non contact force?
Force can be both contact or non-contact
What determines the size of a frictional force?
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.
Is electrostatic force a contact or non contact force?
Electrostatic Force are non-contact force.
Give 3 examples of contact forces?
Normal force: the force exerted by a surface to support the weight of an object resting on it. Frictional force: the force that opposes the motion of two surfaces in contact with each other. Tension force: the force experienced by an object that is being pulled or stretched by a rope, cable, or similar object.
