Question

an object thrown at a certain angle to the ground moves in a curved path and falls back to the ground. the initial and the final points of the path of the object lie on the same horizontal line. what is the work done by the force of gravity on the object​

Answer 1

Answer:

Explanation:

The amt of work done by the force of gravity on the object is 0. This is bc, the total displacement of the object is in the horizontal line, while the force of attraction acts in vertical direction..... i.e in perpendicular way.........

Answer 2

Answer:

since the body returns to a points

which is on the same horizontal

line through the point of

projection no displacement has taken place against the force of gravity therefore, on work is done by the force due to gravity.
