What type of contact force is perpendicular to the surface of contact?
Normal force is the component perpendicular to the surface in mechanics. It prevents an object from penetrating the surface with the contact force exerted.
Is The pressure exerted on an object by a fluid always parallel to the surface of the object?
No. It is not.
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
Is friction a contact or non contact force?
friction is a contact force
What object has high air resistance?
The air resistance on any object depends upon 2 factors these are:Surface area of the object i.e;the more the surface area the more will be the air resistence as most of the air is comming in contact with the body of the surface and thus more resistant is the body to the air.Secondly,the speed at which the object is moving i.e:the more the speed the greater will be the air resistance exerted on an object.
What type of contact force is perpendicular to the surface of contact?
Normal force is the component perpendicular to the surface in mechanics. It prevents an object from penetrating the surface with the contact force exerted.
List two properties of the pressure exerted on an object by a fluid?
The pressure increases as the object goes deeper into the fluid; the pressure is always perpendicular to the surface of the object
Is The pressure exerted on an object by a fluid always parallel to the surface of the object?
No. It is not.
How does pressure exerted by a solid object on a surface differ from pressure exerted within a liquid or a gas?
The pressure exerted by a solid object is in only one direction.
How does pressure exerted by a solid object on a surface differ from pressure exerted within a gas or liquid?
The pressure exerted by a solid object is in only one direction.
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
What is non-contact frce?
Non-contact forces are forces exerted on an object by another object which is not in contact with it, a good example being gravitational force.
When does the shadow of an object short?
When the line from the light source to the surface on which the shadow falls is perpendicular to that surface.
A block is connected to the surface of a table via a string and an electric field is switched on perpendicular to it what will be the tension in the string when it becomes parallel to the field?
In order to know how much tension is on an object, you need to know how much force is being exerted by the object. The formula needed to find out how much force is on an object is T1F1.
Definition of normal force?
Normal Force- this is the support force exerted on an object in contact with another stable object.
Does the surface area of an object affect the amount of friction between the object and the surface?
No, it doesn't, the only important thing is the force perpendicular to the surface (weight) and friction coefficient.
Is friction a contact or non contact force?
friction is a contact force
