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

the rate change of momentum is directly proportional to force

T

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

L
Luca Parisi

Newton's second law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration. Mathematically, it can be expressed as F = m*a, where F represents the force, m is the mass of the object, and a is its acceleration.

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.

States that the rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts

Force is equal to mass multiplied by acceleration:


F = ma

M

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

O

The resultant force acting on an object is proportional to the rate of change of momentum for that object. It also means that F=ma so a resultant force on an object will cause it to accelerate.

Newton’s second law states that the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object. The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body.

Resultant force = mass x acceleration (F = m * a) - the change of momentum is directly proportional to the force.

Rate of change of momentum is directly proportional to the resultant force, and in the same direction.

resultant force= mass x acceleration


The acceleration of an object is proportional to the resultant force on it and inversely proportional to the objects mass.


Which means:


An objects acceleration is directly proportional to the resultant force acting on it. The object accelerates as a result of the resultant force. If the resultant force is bigger that means it will accelerate more.


An objects acceleration is also dependent on its mass but its inversely proportional which means the larger the mass the smaller the acceleration.
