Newton's 1st Law Flashcards
1
Q
What is Newton’s 1st law?
A
An object remains in the same state of motion unless a resultant force acts on it.
- A stationary object stays stationary.
2
Q
If the resultant force is 0 what is the object?
A
- Stationary
- Travelling at a constant speed
3
Q
What is newton’s 2nd law?
A
Acceleration of an object in the direction of the resultant force depends on:
- Size of force
- Mass of objects
4
Q
What is the equation of Newton’s 2nd law?
A
F =ma
5
Q
How do you calculate force?
A
Mass x Acceleration
6
Q
How do you calculate acceleration?
A
Force / Mass
7
Q
How do you calculate mass?
A
Force / Acceleration
8
Q
What is Newton’s 3rd law?
A
When two objects interact, they exert equal and opposite forces on each other.
