When a force moves objects over a rough horizontal surface at a constant velocity the work done against friction must?
When a force moves objects over a rough horizontal surface at a constant velocity, the work done against friction must be equal to the work done by the applied force to maintain the constant velocity. This is because the force of friction opposes the motion of the object, so the work done by the applied force must overcome the work done by friction to keep the object moving at a constant speed.
What is the formula for calculating the work done by friction?
The formula for calculating the work done by friction is: Work Force of friction x Distance.
A 5.0 kg block of ice at -1.5C slides on a horizontal surface with a coefficient of kinetic friction equal to 0.058 The initial speed of the block is 6.0 ms and its final speed is 5.5 ms.?
Assuming that all the energy dissipated by kinetic friction goes into melting a small mass m of the ice, and that the rest of the ice block remains at -1.5°C, determine the value of m.
How can one determine the work done by friction in a given scenario?
To determine the work done by friction in a scenario, you can calculate the force of friction acting on an object and multiply it by the distance the object moves in the direction of the frictional force. This will give you the work done by friction in that scenario.
What is the work done by static friction always dependent on?
The work done by static friction is always dependent on the displacement of the object it acts on.

The work done by static friction is always dependent on the displacement of the object it acts on.
How to calculate the work done by friction in a given system?
To calculate the work done by friction in a system, you can use the formula: Work Force of friction x Distance. First, determine the force of friction acting on the object. Then, multiply this force by the distance the object moves against the frictional force. This will give you the work done by friction in the system.
What can be done to increase the speed of rotation of the coil?
To increase the speed of rotation of the coil, you can increase the voltage applied to the coil or reduce the resistance in the circuit. Additionally, using a stronger magnetic field or reducing the friction in the system can also help increase the speed of rotation.
Is the work done by friction always negative?
No, the work done by friction can be either positive or negative, depending on the direction of the force and the displacement of the object.
When work is done what happens with the energy?
"Work" refers to a transfer of mechanical energy. There is work when you apply a force over a certain distance. What happens to the energy depends on the situation - it may be absorbed by friction (and converted to heat), it may speed an object up (kinetic energy), it may increase the receiving object's potential energy, etc.
Is friction produced when work is done?
Yes, friction is produced when work is done. When two surfaces rub against each other, heat is generated due to the resistance caused by friction. This results in the conversion of some of the work done into thermal energy.
How does the work done on a sliding block with friction affect its potential energy?
When work is done on a sliding block with friction, it can either increase or decrease the block's potential energy, depending on the direction of the force applied. If the work is done against the force of friction, the potential energy of the block increases. Conversely, if the work is done in the direction of the force of friction, the potential energy of the block decreases.
What happens when work is done on a object?
When work is done on an object, it gains energy in the form of kinetic energy or potential energy depending on the type of work done. The object's speed, height, or deformation may change as a result of the work done on it.
