Force and accerlation Flashcards
1
Q
Newtown’s first law
A
If a body is at rest or moving with uniform velocity, it will continue to move with uniform velocity unless there is an external force that makes it behave differently
2
Q
Newtons second law
A
Force is always = to mass * acceleration (N)
3
Q
What is inertia
A
It is the resistance of an object to change its current velocity whether it is at rest or moving with constant velocity
4
Q
W=
A
mass* gravity (N)
5
Q
Newtons third law
A
If an object exerts a force on another object, the other object will exert an equal but opposite force
6
Q
What affects inertia
A
the mass of the object
