Answer:
A box is pushed along the ground with a force of 20 N. If the box is pushed 0.5 m, how much work is done on it?
10 Joules
Explanation:
Work done= Force X distance
hence;
W.D= 20 X 0.5
W.D= 10J
Work is measured in Joule. 10 J of work is done to push the given box along the ground.
Work:
It is measure of change in energy to displace object by applying an external force. Work is equal to the product of the force and displacement. Work is measured in Joule.
W = F.d
Where,
W- work
F- force = 20 N
d - displacement = 0.5 m
put the values in the formula,
W = 20 x 0.5
W = 10 J
Therefore, 10 J of work is done to push the given box along the ground.
