Forces Flashcards
What is a gravitational force
Forces between mases
What are forces measured in
Newtons after sir Isaac Newton
What is an electrical force
They exist between charges
What is a magnetic force
The exist between magnetics
What is weight
*weight = force toward the centre of the earth
What is mass
Mass is the amount of matter
Does the mass ever change
No not even if u move to a planet where weight =0
Why is the weight bigger in a larger mass
Because there is more gravity pulling it toward the earth
What is mass meseured in
Kg
What is earths gravity field
1kg Is pulled with 10N
What is gravitational field strength
How strongly an object is pulled down
What is the equation for earths gravity fields
g=10N per kg (n/kg)
How do u find a total force
Multiply mass In kg by 10
What is the equation for calculating a force
Weight=mg
