Work = Force * Displacement.
Therefore Force = Work / Displacement
= 160 J / 8 m
= 20 N
(Note that the force and the displacement have to be in the same direction, or else the components of either of them will have to be calculated in the direction of the other)
Work = (force) x (distance) Force = (work) / (distance) Force = (160 / 8) = 20 N
depends on friction
20N
A force is needed to move an object.
kinetic frictional
Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.
The force that keeps objects moving in a circle is known as the centripetal force, which acts towards the center. The velocity of the object moving in a circle will be tangential to the circle.
20N
It takes 160J/8m = 20N Newtons force to do the job.
160j of work was needed in order to move an object 8m acroos a floor what was the force in N that was needed to do this job? i think it may be not sure but 20N dont agree with me just maybe your imput will be different
A force is needed to move an object.
Since the object is moving at a constant speed, the net force on it must be zero.If I'm applying a constant horizontal force, then the frictional force must be equal to my force = 600N and in the opposite direction to my force.
how much force is needed to hold the 2kg object
. The amount of Force needed to make an object change its motion depends on the Mass of the object and the Force required
Yes, force of some kind is always needed to slow an object's movement.
acceleration
an unbalanced force
Friction
The main of force needed tio move an object is the objects mass, f= ma.
