Mass and Weight Flashcards
1
Q
mass
A
the amount of matter in an object
measured in kg
does not change with location
2
Q
weight
A
is a force due to gravity
measured in N
changes with location
3
Q
Weight =
A
Mass x Gravity
4
Q
Force =
A
Mass x Acceleration
5
Q
what does acceleration do
A
it tells us how quickly the speed changes (the amount that speed changes per secon)
6
Q
if a box is 2kg, there is a 8N force pulling it east and a 6N force pulling it west
A
the resultant force would be 2N east, and the acceleration, would be 2/2 = 1m/s
7
Q
if there are equal forces pulling an object on opposite sides
A
the object will be at rest or moving in a constant speed
8
Q
free fall
A
it is a regular fall, but without air resistance, this means that a feather and a ball would fall at the same time
