What if two children push a swing at the same time? Would the swing go higher? Yes, together their force would be more. It is common for forces to be combined. Most objects on Earth have at least two forces acting on them. Do you know what one of them is? Of course, that force is gravity. How many forces do you have on you right now? Gravity pulls you down toward the center of Earth. Your legs exert a downward force. They hold you up against the pull of gravity. Consider the example in Figure 1.3. A book is resting on a table. Gravity pulls the book downward. It has a force of 20 newtons. At the same time, the table pushes the book upward. Its force is also 20 newtons. The table opposes the pull of gravity. 

Based on the paragraph, does the response "Downwards" correctly answer the question "What direction is the force of a table on a book that is resting on it?"?

OPTIONS:
- no
- yes
no
Vad händer om två barn trycker på en gunga samtidigt? Skulle gungan gå högre? Ja, tillsammans skulle deras styrka vara mer. Det är vanligt att krafter kombineras. De flesta objekt på jorden har minst två krafter som verkar på dem. Vet du vad en av dem är? Den kraften är naturligtvis gravitation. Hur många krafter har du på dig just nu? Gravitationen drar ner dig mot jordens mitt. Benen utövar en nedåtriktad kraft. De håller dig mot tyngdkraftens dragningskraft. Tänk på exemplet i figur 1.3. En bok vilar på ett bord. Gravitationen drar boken nedåt. Den har en styrka på 20 newton. Samtidigt trycker bordet boken uppåt. Dess styrka är också 20 newton. Bordet motsätter sig tyngdkraftens dragning. Med utgångspunkt i stycket, svarar svaret "Nedåt" korrekt på frågan "Vilken riktning är kraften i ett bord på en bok som vilar på den?"? ALTERNATIV: - nej - ja

Most objects on Earth have at least two forces that act on them. You know what one of them is? That force, of course, is gravity. How many powers are you wearing right now? Gravity pulls you down to the center of the earth. The legs exert a downward force. They're holding you against the gravitational pull. Consider the example in Figure 1.3. A book rests on a table. Gravity pulls the book down. It has a strength of 20 newtons. At the same time, the table pushes the book upwards. Its strength is also 20 newtons. The table opposes the pull of gravity.
