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 the sign of the work done by the frictional force?
The work done by the frictional force is negative because the force opposes the direction of motion. This means that the frictional force removes mechanical energy from the system by transforming it into heat, resulting in a decrease in the object's kinetic energy.
How does the direction of frictional force compare to the direction of an object motion?
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.
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 hockey puck has a coefficient of kinetic friction of mk .1-. if the puck feels a normal force (fn) of 5N what is the frictional force that acts on the puck?
This type of problems about friction are extremely simple: You just multiply the normal force by the coefficient of friction to get the frictional force.
Is writing on a paper a frictional force or muscular force?
i am sure that it is not frictional force.....
On what does the frictional force depend?
Frictional force depends on the nature of the surfaces in contact and the force pressing them together.
What determines the size of frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.
What determines the size of a frictional force?
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.
Which frictional force is self adjusting force?
The static frictional force is a self-adjusting force. It increases or decreases to match the applied force, preventing the object from moving until the maximum threshold is reached.
What has frictional force needed to start an object at rest into motion?
The frictional force needed to start an object at rest into motion is the static frictional force. This force must be overcome by an external force before the object can start moving. Once the object is in motion, the kinetic frictional force will oppose its movement.
What does the frictional force vs normal force graph reveal about the relationship between these two forces?
The frictional force vs normal force graph shows that there is a linear relationship between the two forces. As the normal force increases, the frictional force also increases proportionally. This indicates that the frictional force is directly proportional to the normal force.
Will the kinetic frictional force change if you pull with the same applied force at a new angle?
Yes, the kinetic frictional force will change if you pull at a new angle. The frictional force is influenced by the component of the applied force parallel to the surface. Therefore, changing the angle will alter this component and affect the kinetic frictional force.
What frictional force?
Frictional force is the force that opposes motion between two surfaces.
What is the resistance force of frition?
Frictional Force
What relationship exists between the static frictional force and the normal force of an object?
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.
What is the frictional force needed to slow an object in motion.?
kinetic frictional
