What force works in the opposite direction of travel?
Drag is the force that acts opposite to the direction of motion. It tends to slow an object.
When the force and displacement are in the opposite direction then the work is?
If the force is in the opposite direction of displacement, the work done by the force is negative.
When the force acting on an object is in opposite direction to the direction of its motion the work done is?
Your force is in the opposite direction as the movement. This is the opposite situation from the one above: the moving goalie net has kinetic energy, but loses kinetic energy as you slow it down. In this case, work is negative as the force applied to the goalie net is in the opposite direction of the net’s movement.
What is work done by centripetal force?
The work done by centripetal force always zero as it is perpendicular to velocity and hence instantaneous displacement.
What is work done by frictional force?
The work done by friction is the force of friction times the distance traveled times the cosine of the angle between the friction force and displacement; hence, this gives us a way of finding the distance traveled after the person stops pushing.
What is the work done by centripetal force in circular motion?
In circular motion, work done by centripetal force is zero.
What is work done by centripetal force in uniform circular motion?
Notes: The work done by Centripetal Force in case of Uniform Circular Motion is zero. The displacement and force are mutually perpendicular to each other in case of centripetal force. Therefore the work done is zero.
What is the work done by the frictional force on an object when dragged along a rough surface?
Frictional force is always opposing the relative motion of the body. When a body is dragged along a rough surface, the frictional force will be acting in the direction opposite to the displacement. Thus, the work done by the frictional force will be negative.
Why does displacement take place in the opposite direction of motion?
If displacement is against the force applied ,the applied force does a work. (—work ) But consider why the displacement will take place in opposite direction? ,There can be a situation where the object will be moving opposit to the direction of the force with certain Vel. before the force was applied. The object then was having KE
What is the work done by a force on an object?
The work done by a force on an object can be positive, negative, or zero, depending upon the direction of displacement of the object with respect to the force.
What is the distance a force of 10 N acts through?
A force of 10 N acts through a distance 10 m in the direction of the force.Calculate the work done by the force? A box is dragged along the floor by the rope which makes an angle 30° with the horizontal. The force applied by the rope is 100 N and box is dragged by 10 m.Calculate the work done by the force?
What happens if the force is applied and displacement is negative?
If the force is applied and the displacement is in opposite direction, the work is negative. Work is the scalar product of force and displacement vectors, F*s, where F is the force applied and s is the displacement. Work is a scalar quantity, similar to energy.
