g Calculate the stone’s acceleration. (Its mass is 0.80 kg.)

Exercise P3.5 Mass and weight 27

Mass and weight are two quantities that can easily be confused. How well do you understand the difference between mass and weight? In the second column of the table, write ‘mass’ or ‘weight’ (or ‘both’), as appropriate. Description a force measured in kilograms measured in newtons decreases if you go to the Moon a measure of how difficult it is to accelerate a body caused by the attraction of another body increases if more atoms are added to a body balanced by the contact force of the floor when you are standing makes it difficult to change the direction of a body as it moves decreases to zero as a body moves far from the Earth or any other object

Mass or weight or both?
