1
Q
What is Newton’s first law of motion?
A
An object at rest stays at rest unless acted upon by an unbalanced force, objects in motion stay in motion at the same speed and direction unless acted upon by an unbalanced force
2
Q
What is Newton’s second law of motion?
A
Acceleration of an object is directly related to the net force and inversely related to its mass
F = ma
a = F/m
m = F/a
3
Q
What is Newton’s third law of motion?
A
Stars for every action there is an equal and opposite reaction
4
Q
What is gravitational force?
A
The attractive force between any 2 objects due to their mass. Determined by mass and distance, increases as mass increase, decreases as distance increases.
