When a body is at rest there is no force acting on it?

Answer: If an object is at rest, then there are no forces acting upon the object. It would take an unbalanced force to keep an object in motion at a constant velocity. It is the natural tendency of all objects to eventually come to a rest position.

What happens when there is no applied force?

An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity. Now we come to the case when the net force on an object is not zero. Newton’s Second Law states: F = ma.

What happens to a body originally at rest when force is applied on it?

Initially the body is at rest. So it is said that if we apply a force and this applied force becomes equal to the frictional force then the body will move with constant velocity.

When there is no applied force the force of friction is?

Static friction is friction without sliding, that is no motion. It is equal to the applied force horizontal to the surface the object sits upon. Since there is no resultant force, there is also no static friction. So, zero friction.

When body is at rest which is true?

A body is said to be at rest if it does not change its position with respect to the reference point.

What is the nature of the reaction force if the force acting on a body is gravitational in nature?

It is given the nature of action force acting on a body is gravitational. Based on the concept of motion’s third law given by Newton, we can say that the nature of reaction force will also be the same as that of action force. So, the correct answer is “Option B”.

When a body is at rest force of friction is equal to the applied force True or false?

Explanation: force of friction between two surfaces when the body is in static condition is called static friction and is equal to the applied force.

What is applied force?

An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The normal force is the support force exerted upon an object that is in contact with another stable object.

When body is at rest force of friction is more than the applied force?

Answer: No, it is not necessary that the stationary object will move always when a force is applied. Hence, the stationary object will move only if the applied force is greater than the friction force between the object and the ground.

Which statement describes completely a body in motion?

Answer: Newton’s first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion.

Can a body be at rest and in motion at the same time?

Yes, an object can be at rest with respect to one object and can bein motion with respect to one object and can be in motion with respect to another object. Thus rest and motion are relative terms.

When force acting on a body has an equal and opposite reaction?

According To Third Law Of Motion When A Body Exerts Force On Another Body Then Then The Other Body Also Exerts Force And Both Are Equal And Opposite. So When Earth exerts Force On A Falling Apple Then The Force Of Same Magnitude Should Be Exerted By Apple Also Towards Earth.

Does being at rest mean there is no friction force?

No, if a body is at rest doesn’t mean there is no friction force acting on the body. Take a case, the object is placed on an inclined surface, that time too no force is applied, net external force is zero but there is a friction force (up the slope) which is equal to component of mg in the direction of inclined surface (down the slope).

What is the net force of friction on a body?

friction is a contact force acting along the surface of contact. if a body is at rest then net force on it is 0. total force along the surface is 0 means, friction = applied force.

What is the scope of static friction if the body remains at rest?

Since the body continues to remain in state of rest in this case, there isn’t any force acting on it. But if there is a force acting on it and still the body remains at rest, that implies Static Friction is acting on it. However, it has been explicitly mentioned in the question no force is applied, and hence no scope of static friction.

Which force acts on a body at rest?

A body at rest need not be acted upon by any force. Now, consider a situation where an object is at rest on a rough horizontal floor. You exert a force ( on the object ) that is directed parallel to the surface the object is in contact with. In the case where the object does not slide, static friction is responsible for balancing your force.
