F=ma

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

L

Newton's second law states that force is the rate of change of momentum.

This mathematically simplifies to F = ma in scenarios where the mass of the object does not change (so for example would not apply to rockets where their mass changes quickly). When using F = ma be aware that F is the resultant force on an object, m = its mass, and a = the acceleration the object experiences.

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.

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

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

F=ma (Force = mass x acceleration). If u push or pull something it speeds up depending on how heavy the object is and how hard you push or pull.

The defining equation for Newton’s 2nd Law is F=ma. This essentially states that the resultant force acting on an object (F) in Newtons is equal to its mass (m) in kg multiplied by its acceleration (a) in ms^-2

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 resultant force acting on a body produces acceleration in the direction of this force. This acceleration is directly proportional to the applied force, and inversely proportional to the mass of body.

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

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

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.

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.

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