Is the work done on a system negative in the given scenario?
In the given scenario, if the force applied to the system is opposite to the direction of the displacement, then the work done on the system is negative.
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.
How much work is done by the normal force in a given scenario?
The work done by the normal force in a scenario is zero, as the normal force is perpendicular to the direction of motion and does not contribute to the displacement of the object.
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.
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.

What is the minimum work needed to push a 380-kg car 170 m up a 7.5º incline with friction?
The work done against gravity is given by: W = mgh = (380 kg)(9.8 m/s^2)(170 m)sin(7.5º) The work done against friction is given by: W_friction = f_friction * d = µ * m * g * d, where d is the distance moved. The total work done is the sum of the work against gravity and friction: Total work = W + W_friction.
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.
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 will you know that work is done on an object?
Work is done on an object when a force causes the object to move in the direction of the force. The amount of work done is calculated by multiplying the force applied by the distance the object moved in the direction of the force. Work done transfers energy to or from the object, causing a change in its kinetic or potential energy.
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.
All work done within a geoexpt scenario is saved to a?
Geodatabase
What happens to work done by friction if the speed doubles?
If the speed doubles, the work done by friction remains the same. Friction depends on the force between surfaces and the distance they move relative to each other, not the speed.
