Weight, Mass and Gravity Flashcards
1
Q
What is mass
A
The amount of matter in an object
2
Q
What is weight
A
the force acting on an object due to gravity.
3
Q
What does gravitational field strength depend on?
A
- Location
- The closer you are to the mass causing the field the stronger the Graviational field strength
- The larger the mass the stronger it is
4
Q
What is weight dependant on
A
Gravitational field strength
5
Q
What is weight measured in
A
calibrated spring or Newtonmeter
6
Q
What is mass measured in
A
Kg with a mass balance
7
Q
Formula for Weight
A
Weight(N)= Mass)Kg) x Gravitational Field Strength (N/Kg)
8
Q
What causes the force weight
A
the gravitational field around the earth
9
Q
What is it meant by an objects centre of mass
A
The single point where an objects weight can be considered to act through
10
Q
What piece of equipment can be used to measure an objects weight
A
a calibrated spring balance or newton metre
