If you push a 900N refrigerator with the same force as you lift a 40N dumbbell, the dumbbell will move faster. which of Newton’s laws is this an example of? Explain how you know please. i know it's not the 3rd law.

Newton's second law. The heavier object has more mass, and acceleration is direc tly proportional to force and inversely proportional to mass.

Thankyou so much dude!

I thought it was the third!?

If you push a 900N refrigerator with the same force as you lift a 40N dumbbell, the dumbbell will move faster. According to Chapter 12, which of Newton’s laws is this an example of? Explain how you know.

This is an example of Newton's second law of motion. Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be mathematically expressed as F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.

In this scenario, the force applied to both the refrigerator and the dumbbell is the same. However, the mass of the dumbbell is significantly smaller than the mass of the refrigerator. Therefore, according to Newton's second law, the acceleration of the dumbbell will be greater as it has less mass to resist the force.

Since acceleration is the rate at which an object changes its velocity, we can conclude that the dumbbell will move faster compared to the refrigerator when the same force is applied. This observation aligns with Newton's second law, making it the applicable law in this situation.
