Question 1.

Bericht van Admin op wo sep 07, 2016 9:41 pm

Three forces that act at a distance are: gravitational force, magnetic force and electric force.
Gravity: an object falls towards the ground.
Magnetic force: cans are removed from household rubbish using magnets at a waste disposal plant.
Electric force: in winter an electrically charged object such as a comb or jumper attracts scraps of paper due to static electricity.
