To simplify the experiment and the results
It will stay at rest.
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.
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.
Frictional force depends on the nature of the surfaces in contact and can vary based on surface roughness, temperature, and the presence of lubricants. It does not depend on the surface area in contact but relies on the normal force acting between the surfaces. Frictional force can also generate heat and wear on the surfaces in contact, leading to energy loss and decreased efficiency in mechanical systems.
The vector sum of all applied and frictional forces on an object is the net force acting on the object. This net force determines the object's acceleration according to Newton's second law, F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.
Equilibrium is a state in which all forces acting on an object are in balance.
The total value of the frictional forces acting on the bike and its rider would be 400 N, which is equal in magnitude to the pedal force applied. This is necessary to balance the pedal force and maintain a constant speed when the bicycle is moving at a constant velocity.
It will stay at rest.
The object will experience a frictional force equal in magnitude but opposite in direction to the applied force. The net force acting on the object will be the difference between the applied force and the frictional force. This net force will cause the object to accelerate or move at a constant speed depending on the balance of forces.
Gravitational force,Frictional force of air..........
It will stay at rest.
Yes, in addition to the frictional force of the road, there is the force of gravity acting on you as you run. Gravity pulls you downward towards the Earth's center, while the frictional force opposes the motion between your feet and the road surface.
F = Ma but the acceleration will be in the opposite direction to that of the object's on which friction force is experienced.
The static frictional force is directly proportional to the normal force acting on an object. As the normal force increases, the maximum static frictional force that can be exerted on the object also increases.
An angle can affect friction by changing the normal force acting on an object. When an object is on an inclined plane, the normal force is reduced, which can affect the frictional force acting on the object. As the angle increases, the component of gravitational force acting parallel to the surface also increases, which can increase the frictional force to prevent the object from sliding.
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, velocity does not directly affect frictional force. Frictional force is primarily dependent on the nature of the surfaces in contact and the normal force acting between them. However, velocity can indirectly impact frictional force by generating heat due to more rapid motion, which can affect the coefficient of friction between the surfaces.
