Newton's First And Second Law Flashcards
1
Q
What is a Newton’s first law
A
It is that a resultant force I needed to make something to start moving speed up or slow down.
If the resultant force on a stationary object is zero, the object will remain stationary. If the resultant force on a moving object and zero, it’ll just carry on moving at the same velocity

Q
What is Newton’s second law?
A
Force = mass x acceleration
N kg m/s2

Q
Why can large deceleration be dangerous?
A
As they can can cause serious injuries
Using collisions zones which reduces force. Crumple zones are at the front and back of the Vehicle which crumple in a collision
