CALCULATION OF WORK DONE AGAINST GRAVITY
Suppose you lift an object of mass 1kg from the ground to a height of 1m, the work done in lifting the abject is calculated by using the formula Mgh
Mgh = 1 x 1 x 9.8 joules (g = 9.8m 152) joule is the unit of work.
BALANCED AND UNBALANCED FORCES
When an object is stationary, the forces acting on it.... View More
