newtons 3 laws - Sp2 Flashcards
1
Q
name newtons first law
A
Balanced forces = no resultant force so there is no change in velocity
2
Q
what do no resultant forces produce
A
no change in velocity
3
Q
What is newton’s second law?
A
Unbalanced forces = a resultant force, hence, a change in velocity (acceleration)
4
Q
what happens when the resultant force acting on an object is large
A
thereis a larger change in velocity. the object accelerates at a higher rate (force and the acceleration are directly proportional)
5
Q
name newton’s 3rd law?
A
Forces come in pairs (everything has an equal and opposite reaction)
