If the force acting on abody is doubled, then acceleration becomes
Correct answer: B. Doubled
- A. Half
- B. Doubled
- C. One fourth
- D. Constant
Explanation
According to Newton's Second Law of Motion, expressed as F = ma, the force applied on an object is equal to the mass of the object multiplied by its acceleration. This means that acceleration (a) is directly proportional to the force (F) when mass (m) is constant. Therefore, if the force is doubled, the acceleration must also double to maintain the balance of the equation. Hence, the correct answer is that the acceleration becomes doubled. Other options are incorrect as they propose either an inverse relationship or no change in acceleration, which contradicts the principle of direct proportionality stated in Newton's Second Law.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
