Viscosity opposes the motion of an object through liquid.
The property of resistance of motion (flow) through a liquid is called viscosity.
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
No. Water is a transparent liquid. Opaque means you can't see through an object or substance.
In fluid dynamics, drag (sometimes called air resistance or fluid resistance) refers to forces that oppose the relative motion of an object through a fluid (a liquid or gas).Drag forces act in a direction opposite to the oncoming flow velocity.[1] Unlike other resistive forces such as dry friction, which is nearly independent of velocity, drag forces depend on velocity.[2]For a solid object moving through a fluid, the drag is the component of the net aerodynamic orhydrodynamic force acting opposite to the direction of the movement. The component perpendicular to this direction is considered lift. Therefore drag opposes the motion of the object, and in a powered vehicle it is overcome by thrust.In astrodynamics, and depending on the situation, atmospheric drag can be regarded as an inefficiency requiring expense of additional energy during launch of the space object or as a bonus simplifying return from orbit.
the amount of motion of each molecule increases. i.e the amount of disorder increases. since the motion is increasing as an object gets converted from solid to liquid to gas, the energy level increases.
motion of free falling object does not have friction, while motion of the cart has force of friction
Yes
friction
Friction.
Friction .
resistance (friction)
Friction.
Air resistance
the amount of air resistance on an object depends on the size, shape, and speed of the object. Air resistance is the force that opposes the motion of objects through air.
friction is the answer
For an object moving through the liquid or gas that force is drag.
Air Resistance is the kinetic friction of the object's surface moving through the air. In aeronautical terms this is known as drag.
