What direction does the force of friction act when a body slides?
In the direction opposite to that of the sliding body.
What will happen to the value of friction force when external force acting on the body with mass m is increased from zero to F max such that there is impending motion at F max?
The value of the friction force will increase to match and oppose the external force up to a maximum value known as the static friction force. Once the external force exceeds the maximum static friction force, the object will begin to move, and the friction force will decrease to the kinetic friction force, which is generally lower than the maximum static friction force.
When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
What is the direction of friction forces?
opposing the motion
Why a force acting on a body is called a sliding vector?
A force acting on a body is not typically called a "sliding vector." The term "sliding vector" may refer to a force vector that is parallel to a surface, which could cause the body to slide if it overcomes static friction. The force could also be called a frictional force if it opposes the relative motion of the body.
How does drag work?
Drag force, or the force of air friction for a falling body, increases with speed. A falling object will reach a speed at which the force of air friction will be equal to and opposite the force of gravity. At that point, the object will no longer accelerate. It's speed will remain constant, and we call that speed (and direction) its terminal velocity.
What factor does the limiting value of the force of the static friction depend?
limiting friction is force of friction when a body slides over the surface of another body
When a body slides or rolls over the other body the force of friction is said to be?
When a body slides or rolls over another body, the force of friction is called kinetic friction. This friction arises due to the contact between the surfaces of the two bodies and opposes the relative motion between them.
What is friction and what is meant by maximum friction?
Friction is a force that opposes motion. Maximum friction is the?æ force that must be overcome in order for a body to start moving.?æ Maximum friction is equal to the?æ product of normal force and coefficient of the friction.
When a body is falling freely which force act on it?
When a body is falling freely, the only force acting on it is gravity. This force causes the body to accelerate downwards at a rate of 9.81 m/s^2 near the surface of the Earth.
What direction does the force of friction act when a body slides?
In the direction opposite to that of the sliding body.
What is a force that opposes motion between two surfaced that are in contact?
Friction. More specifically, if the body remains at rest then the opposing force is known as static friction. Whereas, if the body is in motion it is known as kinetic friction.
What is the force that opposes motion?
Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
What force holds you to a sled when it starts moving?
The force that holds you to a sled when it starts moving is friction between your body and the sled, as well as the force of gravity acting on you downwards. As the sled accelerates, friction between your body and the sled helps keep you in place and in motion together.
What is the force that pulls the freely falling body towards the earth is called?
Gravitational Force
What is the maximun coefficient of friction between two surfaces?
friction is the resisting force which oppose the relative motion of two body.cofficient of friction is the ratio of frictional force and normal force of body on surface.thus maximum cofficient of friction defiend as ratio of maximum frictional force or minimum normal force on the surface.
What will happen to the value of friction force when external force acting on the body with mass m is increased from zero to F max such that there is impending motion at F max?
The value of the friction force will increase to match and oppose the external force up to a maximum value known as the static friction force. Once the external force exceeds the maximum static friction force, the object will begin to move, and the friction force will decrease to the kinetic friction force, which is generally lower than the maximum static friction force.
