The body was thrown straight up. Does gravity do the work?
| February 1, 2021 | education
When the body moves upward, gravity does negative work.
Work is determined by the formula: A = F * S * cosα, where F is the force of gravity directed vertically downward, S is the movement of the body directed vertically upward, ∠α is the angle between the direction F and S.
∠α = 180, cos180 = -1, then the mechanical work A will be determined by the formula: A = – F * S.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
