  Question

# Choose the correct statement regarding second law of motion? Statement 1: The law states that whenever a force acts on a particular object, the object will accelerate based on the direction of the force Statement 2: The law states that as long as the mass of an object is constant, increasing the force exerted onto it will also increase its acceleration Statement 3: The law states that force remains constant, and then the increase of the mass of the object will cause acceleration to decrease

A
All statements can be explained by second law of motion
B
Only statement 2 can be explained by second law of motion
C
Statement 2 and 3 can be explained by second law of motion
D
Only statement 1 can be explained by second law of motion.

Solution

## The correct option is A All statements can be explained by second law of motionSecond law of motion states the following: F=m×a Therefore, the object will accelerate based on the direction of the force. When mass is kept constant, F∝a i.e, if the mass of the object is constant, then on increasing the force exerted on the object will also increase its acceleration. m=Fa ⇒m∝1a, when force is kept constant. That is, if the force is constant, on increasing the mass leads to the decrease in acceleration.  Suggest corrections
