What is the 2nd of Newton's laws?

The acceleration of an object is directly proportion to the net force that has been inputted and also depends on the mass of the object.

The force (F) acting on an object is equal to the mass x accelertion so F = m x a. This helps with the First Law as if there is no reultant force F = 0 then m x a must also be equal - the object is not accelerating. An object is not accelerating if it is at rest or moving at a constant velocity. It is helpful for students to undertand both the 1st and 2nd Law using these ideas.

A force applied to an object equals a change in momentum (mass x velocity)

Newton's second law is: F=ma

Where F is force, measured in N

M is mass in kg

and a is acceleration in m/s^2

Newton's second law states that Net Force acting on an object is directly proportional to its acceleration. In mathematical terms

F= ma

where F = net force acting on the object

m = mass of the object

a = acceleration

F=ma

The acceleration of an object depends on the force applied and mass of the object
