True or false:
1. the work done by the gravity does not depend on the path along which an object is taken.
2. mechanical power increases wen the velocity with which the body is pulled increases.
3.when a constant external force acts on the body, its momentum also remains constant.
4.when the sum of the torques is 0, the sum on the force of the body is necesarily 0.
5. when two forces act at different points on a horizontal bar, the bar has no tendency to rotate about a point closer to the bigger force
