P6 Flashcards
A contact force is defined as the force between two objects that are in physical contact. Here are some types of contact force.
Contact force
When an object lies on a surface, the surface exerts an equal and opposite force. The component of this force that is perpendicular to the surface
Normal force
The forces applied to an object in order to displace or deform
Applied force
force experienced by a rope, string, or cable pulled from the opposite end.
Tension force
the force of resistance to an object’s motion. There are two main types of this.
Friction force
when the applied force is such that an object remains stationary relative to the surface.
Static friction
when the applied force is such that it displaces an object, which then moves relative to the surface.
Kinetic friction
It is the resistance offered by the surface when the object is rolling
Rolling friction
It is the resistance to an object’s motion in a fluid.
Fluid friction
The force of resistance offered by air to an object moving through
Air resistance
The force exerted by a spring when compressed or extended
Spring force
When an object is immersed in a fluid, wholly or partially, the fluid exerts an upward force opposite its weight.
Buoyant force
When an object moves through a fluid, like air or water, it experiences a drag force, also known as drag resistance.
Drag force
the force between two objects that are not in physical contact. It is also called a field force.
Non contact force
The force of attraction between the Earth and any other object on its surface
Gravitational force
