Explain how frictional force is used to reduce the speed of a moving object?
Friction is a force that always acts in a direction opposite to that of motion. So the frictional force does negative work on the velocity of an object ( thus reducing the speed of an object).
A feather is in freefall when the force of gravity is greater than the force of air resistance is equal to the force of air resistance is less than the force of air resistance is the only force acting?
"Free fall" means that gravity is the only force acting on a body.
How will the upward force of air resistance compare to the downwward pull of gravity?
Assuming that you're referring to an object that is accelerating towards a massive body by means of gravitational attraction... When the force of frictional air resistance equals the opposing force of gravity, the net force on the object equals zero, and acceleration will cease. It is called terminal velocity, and the object will remain at this velocity until some new event happens.
What is air resistances?
It is the action of friction that slows something moving through air. The larger the object, the more the air resistance acting on the object.
When an object is travelling on the rough surface frictional force is equal to ma?
When an object is moving on a rough surface, the frictional force acting on it is given by the equation F=μN, where μ is the coefficient of friction and N is the normal force. In this case, the frictional force is proportional to the mass of the object (m) and the acceleration (a) it experiences, so F=ma can be used to calculate the frictional force.
What is frictional resistance due to motion through air?
Frictional resistance due to motion through air is the force that opposes the movement of an object through the air. It is caused by air particles colliding with the surface of the object, creating a drag force that slows down the object's motion. The amount of frictional resistance depends on factors like the object's shape, speed, and the viscosity of the air.
When is air resistance is not useful?
It can slow you down because it is a frictional force
What are the examples of contact force?
a contact force includes friction and air resistance
What is the resistance force of frition?
Frictional Force
What are examples of resistance force?
Examples of resistance forces include frictional force between surfaces, air resistance on moving objects, and resistance in electrical circuits that opposes the flow of current.
Which force acts against speed?
Frictional force acts against speed of any object.
What 3 forces slow a bike down?
1. air resistance 2. frictional force 3.
What one of these is not a force gravity magnetism electricity or air resistance?
Air resistance is not a fundamental force like gravity, magnetism, and electricity. It is a type of frictional force that occurs when an object moves through the air and affects the motion of the object.
What are forces on moving object?
The main forces acting on a moving object are gravitational force, frictional force, and air resistance. Gravitational force pulls the object towards the Earth, frictional force opposes the object's motion on surfaces, and air resistance hinders the object's motion through the air. These forces can affect the speed, direction, and behavior of the moving object.
How frictional resistance along a fault affect the force released during an earthquake?
Higher frictional resistance along a fault can inhibit the fault from slipping smoothly, causing stress to accumulate over time. When this stress is eventually released as an earthquake, the force released can be higher if the resistance was greater. Conversely, lower frictional resistance can allow the fault to slip more easily, potentially leading to a lower force released during an earthquake.
What is the fricitional force that opposes the movement of object that fall through the air?
The frictional force that opposes the movement of an object falling through the air is called air resistance or drag. It occurs due to the interaction between the object and the air particles as the object moves through the air. Air resistance slows down the object's descent and reduces its acceleration towards the ground.
What two forces when the bike slowing down a hill?
The two forces acting on a bike slowing down a hill are frictional force, provided by the brakes, and air resistance. Frictional force reduces the bike's speed by applying a backward force on the wheels, while air resistance opposes the bike's motion as it moves through the air.
