2
Q

3

4
Q
What is Newton’s first law?
A
Object stays at rest or in constant motion unless an external force is applied to it
5
Q
What is the second law?
A
External force results in a
F = ma (these two are part of the object)
The net force gives acceleration
Net force is the sum of the forces
6
Q
What is the third law?
A
Every action force has an equal and opposite reaction force that acts on it
Every force is an interaction with another
