Friction's direction is always against the direction work is being applied to.
What else can I help you with?
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.
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.
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.
Does more friction means more work?
No, more friction does not necessarily mean more work. Friction is a force that resists motion, but work is defined as the product of force and displacement in the direction of the force. So, while friction can make it harder to do work in certain situations, they are not directly proportional.
How does friction always work to oppose the direction of velocity?
Friction always opposes the direction of velocity because it acts in the opposite direction to the motion of an object. This resistance is caused by the interaction between the surfaces of the object and the surface it is moving against.
Which direction does friction always work?
Friction's direction is always against the direction work is being applied to.
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.

How does the direction of friction compare to the direction of Motion?
By definition, friction is opposite of the direction of motion.
How does the direction of friction compare to the direct motion?
The direction of friction is opposite to the direction of motion. This means that when an object is moving in one direction, the friction force is acting in the opposite direction, trying to slow down or stop the object.
Does more friction means more work?
No, more friction does not necessarily mean more work. Friction is a force that resists motion, but work is defined as the product of force and displacement in the direction of the force. So, while friction can make it harder to do work in certain situations, they are not directly proportional.
How does friction always work to oppose the direction of velocity?
Friction always opposes the direction of velocity because it acts in the opposite direction to the motion of an object. This resistance is caused by the interaction between the surfaces of the object and the surface it is moving against.
What is the Direction of friction for a rolling body?
The direction of friction of a rolling body is in opposite direction to the motion of the rolling body.
Can workdone by friction be positive?
No, work done by friction is always negative because it opposes the direction of motion. Friction always acts in the opposite direction to the force causing the object to move, resulting in a loss of energy and a decrease in the total mechanical energy of the system.
How does the direction of friction compare with the dierection of the velcocity of a sliding object?
The "force" of friction is always exactly opposite the direction of motion.
How the direction of the force of kinetic friction is related to the direction of an of an objects motion?
Friction always acts opposite to the direction of motion.
