How to Determine the Force Required to Move a Wagon
What law of motion explains why it takes less force to push an empty wagon than a full one?
Which law of motion explains this phenomenon?
O First Law of Motion
O Second Law of Motion
O Third Law of Motion
O Law of Gravity
Answer: Third Law of Motion
Answer
The correct law of motion that explains why it takes less force to push an empty wagon than a full one is the Third Law of Motion.
When an empty wagon is pushed, according to Newton's Third Law of Motion, for every action (force) in nature, there is an equal and opposite reaction. This means that when you push the empty wagon, the ground provides an equal and opposite reaction, making it easier to move compared to a full wagon where the weight adds resistance.
Therefore, the force required to move an empty wagon is less due to the balanced forces acting in opposite directions according to the Third Law of Motion.
