Gravity Flashcards
1
Q
What is gravity?
A
A non-contact force that keeps objects on the surface of Earth
Gravity acts at a distance and is responsible for the attraction between objects with mass.
2
Q
Define mass.
A
The amount of matter within an object (measured in Kg)
Mass is a scalar quantity and does not change regardless of location.
3
Q
What is the weight of an object?
A
The force due to acceleration of gravity
Weight is a vector quantity and varies depending on the gravitational field strength.
4
Q
What formula is used to calculate weight force?
A
F = mg
In this formula, F represents weight force, m represents mass, and g represents acceleration due to gravity.
