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.
Work done against gravity work done against friction?
The work done against gravity is given by the force applied multiplied by the vertical distance lifted. The work done against friction is given by the force applied multiplied by the horizontal distance over which the object moves against the force of friction. Both types of work involve overcoming resistive forces to move an object.
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.
Can work be done by friction?
Yes, work can be done by friction. When an object moves against a surface due to friction, work is done to overcome the resistance offered by the frictional force. This work results in heat production and can cause the object to experience a change in its kinetic 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.

Why when you push an object across a desk the work done is not equal to the change in gravitational potential energy?
In this case, you are not doing work against the force of gravity, but against the force of friction.

What is the force that makes you bicycle brakes work?
The force that makes bicycle brakes work is friction. When the brake pads press against the wheel rim or disc, friction is created, which slows down the rotation of the wheel and ultimately stops the bike.
How are friction and force related?
friction increases the amount of force necessary to do work
Friction is a force which works against what?
motion
Friction can cause a force that pulls on it how?
Friction is always against the direction of the movement.
What force call against moving object?
Friction. Opposing Force
What is created whenever there is friction?
Heat is created whenever there is friction between two surfaces rubbing against each other. This is due to the mechanical work done as a result of the friction force.
