Question 1

Newton’s 1st Law

Answer 1

Objects resist change in motion (inertia).

Question 2

Newton’s 2nd Law

Answer 2

Force = mass x accleration
f=ma

Acceleration happens when a net force is applied.

Question 3

Newton’s 3rd Law

Answer 3

Equal & opposite forces (action-reaction).

Question 4

When does Newton’s 2nd Law NOT apply?

Answer 4

At constant speed, acceleration = 0.

Remember:
No acceleration →
No net force →
Newton’s 2nd Law (F = ma) does NOT apply
