... the integrand of the line integral and a definite path for the mass m must be specified to evaluate the work. 2. The value of the work or line integral does not depend on the path or route taken by the mass as it moves from (i) to (f ). In this case the force is called conservative. Examples are the ...

... 2. As a rocket takes off to the sky, it’s speed increases. Explain why. F = m × a; Newton second law states that acceleration of an object is directly proportional and in the same direction as the applied force, and inversely proportional to its mass. Therefore, as the rocket takes off to the sky, i ...
