Question

If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. which kind of law of motion is there

Answer 1

Answer:

Explanation:

the second law of motion

Answer 2

Newton's 2nd Law of Motion is being used here .

Newton's 2nd law states that force is equal to to the rate of change of momentum. So, mathematically, we can say :

$F=\dfrac{\Delta P}{\Delta t}$

$\implies F=\dfrac{\Delta (mv)}{\Delta t}$

• For constant mass , we can say:

$\implies F=m \times \dfrac{\Delta v}{\Delta t}$

$\implies F=m \times a$

$\implies \: a = \dfrac{ F}{m}$

• For constant force, we can say:

$\implies \: a \propto \dfrac{1}{m}$

So, truck having higher mass than car will have lesser acceleration for equal force.

[Hence explained with 2nd Law of Motion]
