Science Physics Flashcards
1
Q
2nd law
A
Acceleration of an object is directly related to the magnitude and direction of the external force acting upon it
Ball is rolling at a constant force then falls of counter which makes it pick up acceleration
2
Q
3rd law
A
For every action there is an equal or opposit reaction
3
Q
What are four forces in a car
A
Friction
Thrust
Ground reaction
Weight
4
Q
What is the calculation for 2nd law
A
F= m*a
A= f/m
M=f/a
5
Q
What is a net force
A
Is a vector sum of all forces acting on an object
6
Q
What is weight
A
Weight is a force not a mass
7
Q
1st law
A
An object will remain at rest or in a constant motion until an unbalanced external force acts upon it
Egg dropping into water when plate is moved
