Which is one kind of evidence that work is done on an object?
A. The object stays in one place.
B. The object moves some distance.
C. The object has a force on it.
D. The object changes shape.

Answer 1

B. The object moves some distance

Step-by-step explanation:

• Work is the product of force and distance.

• Work is done on an object when a force is applied on the object making it move some distance.
• For example; If a mason applies a force of 5 N to move a stone at a distance of 10 m, then the work done will be 50 Joules.
• Applying a force on an object without making it move some distance then there is no work done.
• Consider a boy pushing a wall really hard and the wall doesn't move even for a single inch, this means there is no work done.
