The net force acting on a body or system is equal to the mass of the system multiplied by the acceleration of the body or system the force is acting on. (F = ma)

Newtons Second law is f = ma, which is the force = mass x Acceleration , Force (Newtons) = Mass (kg) x Acceleration (Metres/ Second)

Force is equal to mass multiplied by acceleration:


F = ma

A
Alessio Rayner

For a body whose mass is constant: F = ma. In other words, the force acting on it is directly proportional to its acceleration. Using SUVAT equations, we can also deduce that force is equal to the rate of change of momentum.

Force on a body is equal to mass times acceleration. F = m * a Newtons

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

S
Sureel Kumar Dohare

F=MA

THE RATE OF CHANGE OF MOMENTUM IS PROPRATIONAL TO THE EXTERNAL FORCE ON BODY along to line of action

force create motion but force is vector quantity which has directional sense

pull and push are kind of direct active force whereas frictional is non conservative force in nature.

It can be summarised as force = mass x acceleration :)

Newton's second law can simply be remembered by the equation F=ma, where F=force, m=mass, and a=acceleration. The acceleration of an object is dependent on two variables the net force acting upon the object and the mass of the object for example; when riding your bike your bicycle would be the mass and your legs pushing the pedals would be the force being applied. When this happens your bicycle starts moving which is acceleration.
