What is an example of Newton's 2nd or 3rd Law in daily life.

Examples of Newton's 2nd Law:

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.

Examples of Newton's 3rd law: When a person pulls down on a vertical rope, the rope pulls up on the person

I think this is more of Physics, not Biology:

2nd law:

Well, have you ever sat in a car, and when the car accelerates fast enough, you get pushed to the back of your seat, and the back of your seat kind of "pushes" you forward? The back of our seat operates force on our back which is proportional to the acceleration and our weight (mass).

The second law basically defines "force" in terms of "mass" and "acceleration". So any situation in which an object changes its velocity involves that law.

3rd law:

For every action, there is an equal and opposite reaction. Let's consider the example of the apple falling on Newton's head. Gravity applies a downard force on the apple. While the apple applies an equal and opposite force upwards to keep the apple "suspended". But when the force becomes too weak to match gravity, it falls downward.
