Question

1. give an example of newtons second law in a real - life application.
2. explain what forces the egyptians had to overcome when building the pyramid

Explanation:

For the first question, Newton's second law ($F = ma$, force equals mass times acceleration) is applied when pushing a car. The more massive the car, the more force is needed to accelerate it. For the second question, when building the pyramids, the Egyptians had to overcome the force of gravity pulling down on the massive stone blocks, as well as frictional forces when moving the blocks.

Answer:

1. Pushing a car. The more massive the car, the more force is needed to accelerate it, following $F = ma$.
2. They had to overcome the force of gravity acting on the heavy stone - blocks and frictional forces when moving the blocks.
