Newton's 2nd law IGCSE

Newton's 2nd law IGCSE

By Franck Maury

(a) is the reference.

single mass m and force F

=> single acceleration a​

​

(b) simple mass m, double force 2F

=​> double acceleration 2a

​

(c) double mass 2m, single force F

=> half ​acceleration a/2

​

​

​Remember: F= ma a=F/m

a is proportional to F and inversely proportional to m​
