A box is sitting on the ground and weighs 100 kg and the coefficient of friction is 0.23. Is it easier to push by applying the f
orce?
1 answer:
Answer:
-No
Explanation:
Given that
Mass of box = 100 kg
Coefficient of friction ,μ= 0.23
We know that friction force depends on the normal force acts on the box
Fr= μ N
When we pull the box then :
Normal force N= mg
Friction force Fr= μ mg
When we push the box :
Lets take pushing force = F
θ =Angle make by pushing force from the vertical line
Normal force
N = mg + F cosθ
Fr= μ ( mg + F cosθ )
The friction force is more when we push the box.That is why this is not easier to push the box.
Therefore answer is ---No

Answer:
forces that are equal in size and opposite in direction. Balanced forces do not result in any change in motion. unbalanced. forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
