160J of work was needed in order to move an object 8m across a floor. What was the force (in N) that was needed to do this job?
To find the force needed to do this job, we can use the work formula:
Work = Force × Distance
Given that the work required is 160J and the distance is 8m, we can rearrange the formula to solve for force:
Force = Work / Distance
Substituting the given values:
Force = 160J / 8m = <<160/8=20>>20 N
Therefore, the force needed to move the object across the floor is 20 N.
Yes 20N
Yes, the force needed to move the object across the floor is indeed 20N.
To find the force needed to do the job, we can use the formula:
Work (W) = Force (F) × Distance (d)
Rearranging the formula, we have:
Force (F) = Work (W) ÷ Distance (d)
Given:
Work (W) = 160 J
Distance (d) = 8 m
Substituting the values into the formula, we get:
Force (F) = 160 J ÷ 8 m
Calculating the division, we find:
Force (F) = 20 N
Therefore, the force needed to move the object was 20 N.
