Which force stops a train when the brakes are applied?
Friction between the brake pads and the train wheels is the force that ultimately stops the train when the brakes are applied. The brake pads create friction by pressing against the rotating wheels, converting the kinetic energy of the train into heat energy as they slow down the train.
What does friction turn into?
Friction converts mechanical energy into heat energy, which is released as objects rub against each other. This heat energy can cause an increase in temperature in the surfaces experiencing friction.
Which type of energy is the mechanical energy of the car converted?
Most of it will be converted to heat, via friction.
What is the work of friction formula and how is it used to calculate the energy dissipated due to friction in a mechanical system?
The work of friction formula is W Fd, where W is the work done by friction, F is the force of friction, and d is the distance over which the force is applied. This formula is used to calculate the energy dissipated due to friction in a mechanical system by multiplying the force of friction by the distance over which it acts.
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 does friction reduce the mechanical advantage in machines?
Because some energy is expended in overcoming the friction and not applied to performing the task which the machine is meant to do.
What does friction turn into?
Friction converts mechanical energy into heat energy, which is released as objects rub against each other. This heat energy can cause an increase in temperature in the surfaces experiencing friction.
When is static friction applied?
Static friction is not necessarily an applied force, but something that occurs when there is an applied force. Static friction occurs when there is no motion and there is a force being applied to an object on a surface.
Which type of energy is the mechanical energy of the car converted?
Most of it will be converted to heat, via friction.
What friction prevents an object from moving when a force is applied?
The friction produced that stops an object moving when force is applied is 'static friction'.
What is the work of friction formula and how is it used to calculate the energy dissipated due to friction in a mechanical system?

How does braking system work with friction?
When the brakes are applied, the brake pads press against the brake rotors, creating friction. This friction converts the kinetic energy of the moving vehicle into thermal energy, slowing down the vehicle. The more friction generated between the pads and rotors, the faster the vehicle will decelerate.
Can static friction be negative?
No, static friction cannot be negative. Static friction always acts in the direction opposite to the applied force and prevents an object from moving when a force is applied. If the external force is removed, static friction drops to zero.
Is friction and static the same?
Limiting friction is the case of static friction where an object is right on the edge of moving, any more force applied to the object will cause it to move. Limiting friction is the largest value that the static friction can take
What is the friction that prevents an object from moving when a force is applied is what friction?
Static friction is the friction that prevents an object from moving when a force is applied. It acts in the opposite direction of the applied force and increases until the force surpasses the maximum static friction force, allowing the object to move.
