8th graders - do your problems for Newton's Second Law:
Newton's 2d Law of Motion is F = m x a
To solve for force, plug the numbers into the formula and do the math.

Ex: What force is required to move a 3 kg box, accelerating it by 2 m/s("s2" means "second squared")?
Answer) F = m x a
                  = 3 kg x 2 m/s2
                  = 6 kg m/s2
                  = 6N

Your turn: solve these problems in your science notebooks:

1) What force is required to move a 5 kg rock, accelerating it by 3 m/s2?

2) What force is generated by a 20 kg TV, accelerating it by 9.8 m/s2?

3) What force is required to move a 100 kg person, accelerating it by 2.5 m/s2?

4) What force is required to move a 2 kg bag, accelerating it by 1 m/s2?

5) What force is required to move a 0.2 kg ball, accelerating it by 5 m/s2?
