Newton’s Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.”
v is the final velocity. u is the initial velocity. t is the time taken. Plugging in the given values, we get a = (20 - 0) / 10 = 2 m/s^2.Use the force equation (F = ma) to find the force required:We have the mass (m) and the acceleration (a), so we can multiply ...

A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Load A weight or source of pressure borne by someone or something The increased load on the heart caused by a raised arterial pressure The arch has...
Acceleration, Force, and Mass In the foregoing chapter we constructed the velocity concept by properly combining space and time, and we thus obtained a new physical entity which plays an important role in the formulation of the laws of nature. But the basic law of na... L Motz,JH Weaver ...

The equation for the formula of Force can be expressed in the form given below: F = ma Where, m = mass a = acceleration It is formulated in Newton (N) or Kgm/s2. Acceleration “a” is given by, a = v/t Where, v = velocity t = time taken So Force can be defined as F = ...
