Xác định lực tại A, B,C của hệ thanh phẳng cho hình vẽ sau: biết BC=BD=AB/2=a=1m; q=2 kN/m; F=qa; M=√2/2

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
