1.7 Weight, Mass and Gravity Flashcards
1
Q

A
The force acting on an object due to gravity
2
Q
Weight is directly proportional to two things. What are they?
A
Mass and gravitational force
3
Q
What is the gravitational force on Earth
A
10 (9,8) N/kg
4
Q
What is the gravitational force on the moon?
A
1.6 N/kg
5
Q
What is the formula for weight?
A
W = m * g
W = weight (N)
m = mass (kg)
g = gravitational field strength (N/kg)
