How Forces affect Motion
PT1 Revision II - How force affects motion
3.
Newton's second law
Question:
3
m.
Numerical problem:
A force acting on an object is doubled while its mass remains unchanged. What happens to the acceleration?
From the
Newton's second law
, We know that,
\(F\ = \frac{m}{a}\)
\(F=m+a\)
\(F=a\times t\)
\(F\ =\ m \times a\)
Acceleration of the object becomes:
Acceleration remains constant
Acceleration becomes half
Acceleration becomes double
Acceleration becomes one-fourth
