Question

open - ended
answer in 1 - 2 sentences.

1. give an example of newtons first law from everyday life.
2. why does a heavier object accelerate less than a lighter one if pushed with the same force?

Explanation:

1. When a car suddenly stops, passengers lurch forward. This is because the passengers tend to stay in motion (as per Newton's First Law) until a force (like seatbelt or dashboard) acts on them.
2. According to Newton's Second Law ($F = ma$, where $F$ is force, $m$ is mass, and $a$ is acceleration), if $F$ is the same, a larger $m$ (heavier object) results in a smaller $a$ (acceleration).

Answer:

1. When a car suddenly stops, passengers lurch forward.
2. According to $F = ma$, with same $F$, larger $m$ gives smaller $a$.
