Examples of normal force include the force exerted by a surface to support an object placed on it, such as the force exerted by the ground on a person standing, or the force exerted by a bookshelf on a book placed on it.
Gravitational force Electrostatic force Magnetic force Nuclear force Tension force Frictional force Normal force Buoyant force Air resistance force Elastic force
Two examples of contact forces are friction and normal force. Friction occurs when two surfaces are in contact and resist an object's movement, while normal force is the force exerted by a surface to support an object resting on it.
Two examples of contact forces are friction, which occurs when two surfaces are in contact and resist motion, and normal force, which is the force exerted by a surface to support an object against gravity.
Examples of contact forces include friction, normal force, tension, and applied force. These forces require physical contact between two objects for them to act upon each other.
Contact force. This force only acts upon objects that are in direct physical contact with each other. Examples include friction, tension, and normal force.
