10. Newton’s 2nd Law Equation
Newton’s 2nd Law gives us an exact relationship between force, mass, and acceleration.
Units
(a) Acceleration m/s2
(m) Mass kg
(F) Force N
Equations
F = ma
a = 𝐅 𝐦
1 N = 1 kg ∙ m/s2

11. Ex1: What is the acceleration of a 3 kg object, if a force of 12 N is used to move it? F = m = a =
a = 4 m/s2

12. Ex2: Brad’s car weighs 1,000 kg and is out of gas
Ex2: Brad’s car weighs 1,000 kg and is out of gas. Brad pushes the car at an acceleration of 0.5 m/s2. What force did Brad push? F = m = a = ?
1,000 kg
0.5 m/s2
F = ma
F = 1,000 kg ∙ 0.5 m/s2
F = 500 kg ∙ m/s2
F = 500 N
