Physics Forces (newtons Law) Topic 2 Flashcards
1
Q
How do you calculate acceleration in a velocity time graphs?
A
The gradient of the line
2
Q
What is terminal velocity?
A
When the force acting against and for are balanced making you fall at a constant speed.
3
Q
What is Newton’s third law?
(This is on the test )
A
Newton’s third law is every action has an equal and opposite reaction
4
Q
What is Newton’s second law?
A
Newton’s third law is force and acceleration which can be substituted with F = a x m
F = force
A = acceleration
M = mass
5
Q
What is Newton’s first law?
A
Newton’s first law is that for an object to move from a constant velocity a resultant force has to act upon it
6
Q
How do you calculate stopping distance?
A
Breaking distance + thinking distance
7
Q
How to calculate momentum?
A
P= MxV
8
