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)
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
To determine the force needed to move the object, you can use the work-energy principle - work done is equal to the force applied multiplied by the distance moved. Given that the work is 160J and the distance is 8m, the force required can be calculated as 160J / 8m = 20N. Therefore, a force of 20N would be needed to move the object 8m across the floor.
The force needed to move the object can be calculated using the formula: Force = Work / Distance. Substitute the given values: Force = 160J / 8m = 20N. Therefore, the force needed to move the object was 20 Newtons.
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
The main reason an object stops when you stop pushing it across the floor is due to the force of friction between the object and the floor. When you push the object, the force you apply overcomes friction and moves the object forward. When you stop pushing, friction between the object and the floor slows it down and eventually brings it to a stop.
The force that slows you down as you slide across the floor is primarily kinetic friction. This force arises due to the interactions between the surfaces of the sliding object and the floor, leading to resistance that opposes the motion.
i wish i knew how
A force is needed to move an object.
The resistance or drag you encounter when pulling an object across the floor is mainly due to friction between the object and the floor surface. This frictional force opposes the motion of the object and makes it harder to move. The rougher the surface or the heavier the object, the greater the resistance or drag will be.
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.
It typically takes more force to slide an object across a surface than to pick it up. When sliding an object, you are working against friction which creates resistance, whereas when picking up an object, you primarily need to overcome gravity.
Yes. Friction is a force that resists the motion of an object moving across a surface. The amount of force needed to overcome friction and move an object a certain distance depends on factors like the roughness of the surfaces in contact and the weight of the object.
